The system can create threads for a system threadpool, so there is
no guarantee that the thread that is stopped is thread 1. So use
a more robust check.

Summary:
The testcase TestNoreturnUnwind.py was failing
because the unwind from the vdso library was not
successful for clang compiler while it was passing
for gcc. It was passing for gcc since the unwind plan
used was the assembly plan and the ebp register was
set by the main function in case of gcc and was not
used by the functions in the call flow to the vdso, whereas
clang did not emit assembly prologue for main and so
the assembly unwind was failing. Normally in case of
failure of assembly unwind, lldb switches to EH CFI frame
based unwinding, but this was not happening for
the first frame. This patch tries to fix this behaviour by
falling to EH CFI frame based unwinding in case of assembly
unwind failure even for the first frame.
The test is still marked as XFAIL since it relys on the fix
of another bug.

-gsplit-dwarf is not implemented by clang on Windows. As such,
all the dwo tests are having the -gsplit-dwarf command line option
completely ignored, and the result is you get regular dwarf debug
information, and it's just running the exact same tests twice,
doubling the length of the test suite for no good reason.

The test hangs/crashes/fails because it does not use the listener API in a way that LLDB expects.
I don't really know if this is the fault of LLDB of the test...

Summary:
On linux we need the process to give us special permissions before we can attach to it.
Previously, the code for this was copied into every file that needed it. This moves the code to a
central place to reduce code duplication.

I prefer to use "-p" over using line_number and then setting by line because it's makes it possible
to see what the breakpoint is at the site where you make the breakpoint. So I switched
it back to -p but specified the source file as well, which is an "all within lldb" way of doing
what Pavel's fix did.

gcc by default does not accept for loop declarations in C files (one must choose C99 mode first,
which we don't). Place the declaration outside the loop, to make this code more conformant.

On locked down systems (such as our buildbot) one needs to do a special dance to allow attaching
to processes. This commit adds this code to the TestBatchMode inferior.

New test introduced in r257120 was failing on linux. The reason for that the regex for setting
the breakpoint was being applied to the "default file", which in this case was the asm file
containing the definition of the sleep() syscall (because after attach, we are stopped in the
sleep function). I have changed this use the more customary way of setting the breakpoint and
specifying the source file name explicitly.

Batch mode is supposed to stop execution and return control to the user when an
exceptional stop occurs (crash, signal or instrumentation). But attach always stops
with a SIGSTOP on OSX (maybe on Linux too?) which would short circuit the rest of the
commands given.
This change allows a command result object to indicate that it expected to leave the
process stopped with an exceptional stop reason, and it is okay for batch mode to keep going.

The lldbinline inline-test mechanism will create a Makefile
if one does not exist in the test directory. This Makefile
and its *.d files were not getting cleaned up after a test run,
leaving trash in the source tree.

The logic for skipping over the stop-and-restart events was incorrect as it was also skipping the
expectations. Implement it properly. No test is affected by this as they were not encountering
these events, but I encountered this issue when trying to use this function in a new test.

This patch adds support the command 'source info' as follows:
(lldb) help source info
Display source line information (as specified) based on the current executable's
debug info.
Syntax: source info <cmd-options>
Command Options Usage:
source info [-c <count>] [-s <shlib-name>] [-f <filename>] [-l <linenum>] [-e <linenum>]
source info [-c <count>] [-s <shlib-name>] [-n <symbol>]
source info [-c <count>] [-a <address-expression>]
-a <address-expression> ( --address <address-expression> )
Lookup the address and display the source information for the corresponding
file and line.
-c <count> ( --count <count> )
The number of line entries to display.
-e <linenum> ( --end-line <linenum> )
The line number at which to stop displaying lines.
-f <filename> ( --file <filename> )
The file from which to display source.
-l <linenum> ( --line <linenum> )
The line number at which to start the displaying lines.
-n <symbol> ( --name <symbol> )
The name of a function whose source to display.
-s <shlib-name> ( --shlib <shlib-name> )
Look up the source in the given module or shared library (can be specified
more than once).
For example:
(lldb) source info --file x.h
Lines for file x.h in compilation unit x.cpp in `x
[0x0000000100000d00-0x0000000100000d10): /Users/dawn/tmp/./x.h:10
[0x0000000100000d10-0x0000000100000d1b): /Users/dawn/tmp/./x.h:10
The new options are used to fix the MI command:
-symbol-list-lines <file>
which didn't work for header files because it called:
target modules dump line-table <file>
which only dumps line tables for a compilation unit.
The patch also fixes a bug in the error reporting when no files were supplied to the command. Previously you'd get:
(lldb) target modules dump line-table
error:
Syntax:
error: no source filenames matched any command arguments
Now you get:
error: file option must be specified.

I'm getting rid of the expected timeouts. I'll XFAIL/skip any tests that show up as failing after
this (I haven't seen any when running locally, but maybe the buildbot will disagree).

I think it was timing out because of the attach deadlocks, which are now fixed. In any case, it
has passed last 200 buildbot runs, so I am enabling it.
llvm-svn: 256748
I believe the cause for this was the attach lockup fixed in r246756. I will enable this tests and
observe the buildbots for signs of problems.

This is generating a SIGSEGV somewhere around 1 in 10 runs on OS X.
Skip the whole test to avoid testbot noise until we can get the
SIGSEGV addressed.
