the process exists.

I also added some tests that crash before this fix, and work correctly after.

b9c1b51e45 *** This commit represents a complete reformatting of the LLDB source code
*** to conform to clang-format’s LLVM style.  This kind of mass change has
*** two obvious implications:

Firstly, merging this particular commit into a downstream fork may be a huge
effort.  Alternatively, it may be worth merging all changes up to this commit,
performing the same reformatting operation locally, and then discarding the
merge for this particular commit.  The commands used to accomplish this
reformatting were as follows (with current working directory as the root of
the repository):

    find . \( -iname "*.c" -or -iname "*.cpp" -or -iname "*.h" -or -iname "*.mm" \) -exec clang-format -i {} +
    find . -iname "*.py" -exec autopep8 --in-place --aggressive --aggressive {} + ;

The version of clang-format used was 3.9.0, and autopep8 was 1.2.4.

Secondly, “blame” style tools will generally point to this commit instead of
a meaningful prior commit.  There are alternatives available that will attempt
to look through this change and find the appropriate prior commit.  YMMV.

377e4213e1 Fixes for platforms that default to unsigned char
This fixes several test case failure on s390x caused by the fact that
on this platform, the default "char" type is unsigned.

- In ClangASTContext::GetBuiltinTypeForEncodingAndBitSize we should return
  an explicit *signed* char type for encoding eEncodingSint and bit size 8,
  instead of the default platform char type (which may be unsigned).
  This fix matches existing code in ClangASTContext::GetIntTypeFromBitSize,
  and fixes the TestClangASTContext.TestBuiltinTypeForEncodingAndBitSize
  unit test case.

- The test/expression_command/char/TestExprsChar.py test case is known to
  fail on platforms defaulting to unsigned char (pr23069), and just needs
  to be xfailed on s390x like on arm.

- The test/functionalities/watchpoint/watchpoint_on_vectors/main.c test
  case defines a vector of "char" and implicitly assumes to be signed.
  Use an explicit "signed char" instead.

e5ee6f04ab Figure out what the fixed expression is, and print it. Added another target setting to
quietly apply fixits for those who really trust clang's fixits.

Also, moved the retry into ClangUserExpression::Evaluate, where I can make a whole new ClangUserExpression 
to do the work.  Reusing any of the parts of a UserExpression in situ isn't supported at present.

863fab69a2 Expose top-level Clang expressions via the command line and the API.
Top-level Clang expressions are expressions that act as new translation units,
and define their own symbols.  They do not have function wrappers like regular
expressions do, and declarations are persistent regardless of use of the dollar
sign in identifiers.  Names defined by these are given priority over all other
symbol lookups.

This patch adds a new expression option, '-p' or '--top-level,' which controls
whether the expression is treated this way.  It also adds a flag controlling 
this to SBExpressionOptions so that this API is usable externally.  It also adds
a test that validates that this works.  (The test requires a fix to the Clang
AST importer which I will be committing shortly.)

a1e541bf9f Use Clang's FixItHints to correct expressions with "trivial" mistakes (e.g. "." for "->".)
This feature is controlled by an expression command option, a target property and the
SBExpressionOptions setting.  FixIt's are only applied to UserExpressions, not UtilityFunctions,
those you have to get right when you make them.

This is just a first stage.  At present the fixits are applied silently.  The next step
is to tell the user about the applied fixit.

4a289a93f7 Remove expectedFailureWindows decorator.
expectedFailureWindows is equivalent to using the general
expectedFailureAll decorator with oslist="windows".  Additionally,
by moving towards these common decorators we can solve the issue
of having to support decorators that can be called with or without
arguments.  Once all decorators are always called with arguments,
and this is enforced by design (because you can't specify the condition
you're decorating for without passing an argument) the implementation
of the decorators can become much simpler

7a5382de82 Move some of the common decorators to decorators.py.
This doesn't attempt to move every decorator.  The reason for
this is that it requires touching every single test file to import
decorators.py.  I would like to do this in a followup patch, but
in the interest of keeping the patches as bite-sized as possible,
I've only attempted to move the underlying common decorators first.
A few tests call these directly, so those tests are updated as part
of this patch.

783550be62 Remove assumptions that thread 0 is always the main thread.
Starting with Windows 10, the Windows loader is itself multi-threaded,
meaning that the loader spins up a few threads to do process
initialization before it executes main.  Windows delivers these
notifications asynchronously and they can come out of order, so
we can't be sure that the first thread we get a notification about
is actually the zero'th thread.

This patch fixes this by requesting the thread stopped at the
breakpoint that was specified, rather than getting thread 0 and
verifying that it is stopped at a breakpoint.

df55f522bd Fix race during process interruption
Summary:
The following situation was occuring in TestAttachResume:
- we did a "continue" from a breakpoint (which involves a private start-stop to step over the
  breakpoint)
- after receiving the stop-reply from the step-over, we issue a "detach" (which requires a
  process interrupt)
- at this moment, the public state is "running", private state is "about-to-be-stopped" (the
  stopped event was broadcast, but it was not received yet)
- StopForDestroyOrDetach (public thread) notes the public state is running, sends an interrupt
  request to the private thread
- private thread gets the eBroadcastBitInterrupt (before the eStateStopped message), and asks the
  process plugin to stop (via Halt())
- process plugin says it has nothing to do as the process is already stopped
- private thread shrugs and carries on. receives the stop event, restores the breakpoint and
  resumes the process.
- after a while, the public thread times out and says it failed to stop the process

This patch does the following:
- splits Halt() into two functions, private and public, their usage depends on the context
  - public Halt(): sends eBroadcastBitInterrupt to the private thread and waits for the Stop
    event
  - HaltPrivate(): asks the plugin to stop and makes a note that the halt was requested. When the
    next stop event comes it sets the interrupt flag on it.
- removes HijackPrivateProcessEvents(), as the only user (old Halt()) has gone away
- removes the m_currently_handling_event hack, as the new Halt() does not need it
- adds a use_run_lock parameter to public Halt() and WaitForProcessToStop(). This was needed
  because RunThreadPlan uses Halt() while holding the run lock and we don't want Halt() to take
  it away from him.

be994649b4 Fix to solve Bug 23139 & Bug 23560
Summary:
 - Reason of both bugs:

   1. For the very first frame, Unwinder doesn't check the validity
      of Full UnwindPlan before creating StackFrame from it:

        When 'process launch' command is run after setting a breakpoint
        in inferior, the Unwinder runs and saves only Frame 0 (the frame
        in which breakpoint was set) in thread's StackFrameList i.e.
        m_curr_frames_sp. However, it doesn't check the validity of the
        Full UnwindPlan for this frame by unwinding 2 more frames further.

   2. Unwinder doesn't update the CFA value of Cursor when Full UnwindPlan
      fails and FallBack UnwindPlan succeeds in providing valid CFA values
      for frames:

        Sometimes during unwinding of stack frames, the Full UnwindPlan
        inside the RegisterContextLLDB object may fail to provide valid
        CFA values for these frames. Then the Fallback UnwindPlan is used
        to unwind the frames.

        If the Fallback UnwindPlan succeeds, then it provides a valid new
        CFA value. The RegisterContextLLDB::m_cfa field of Cursor object
        is updated during the Fallback UnwindPlan execution. However,
        UnwindLLDB misses the implementation to update the 'cfa' field
        of this Cursor with this valid new CFA value.

 - This patch fixes both these issues.

 - Remove XFAIL in test files corresponding to these 2 Bugs
