9388c4703b [testsuite] Split Objective-C new syntax test
This splits the second longest test into separate test cases. Similar to

de11105d2e [lldb] [test] Mark failing tests XFAIL on NetBSD
Add a convenience 'expectedFailureNetBSD' decorator and mark all tests
currently failing on NetBSD with it.  Also skip a few tests that hang
the test suite.  This should establish a baseline for the test suite
and get us closer to enabling tests on buildbot.  This will help us
catch regressions while we still have a lot of work to do to get tests
working.

It seems that there are also some flaky tests.  I am going to address
them later on.

b12ac2b689 Pass arguments correctly to the objc object checker on arm64
Traditionally objc had two entry points, objc_msgSend for scalar
return methods, and objc_msgSend_stret for struct return convention
methods.  But on arm64 the second was not needed (since arm64 doesn't
use an argument register for the struct return pointer) so it was removed.

The code that dispatches to the objc object checker when it sees some
flavor of objc_msgSend was not aware of this change so was sending the
wrong arguments to the checker.

This fixes most references to the paths:
 llvm.org/svn/
 llvm.org/git/
 llvm.org/viewvc/

 github.com/llvm-project/

to instead point to https://github.com/llvm/llvm-project.

This is *not* a trivial substitution, because additionally, all the
checkout instructions had to be migrated to instruct users on how to
use the monorepo layout, setting LLVM_ENABLE_PROJECTS instead of
checking out various projects into various subdirectories.

I've attempted to not change any scripts here, only documentation. The
scripts will have to be addressed separately.

Additionally, I've deleted one document which appeared to be outdated
and unneeded:

2946cd7010 Update the file headers across all of the LLVM projects in the monorepo
to reflect the new license.

We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.

Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

c9e1190a27 [lldb] Retrieve currently handled Obj-C exception via __cxa_current_exception_type and add GetCurrentExceptionBacktrace SB ABI
This builds on https://reviews.llvm.org/D43884 and https://reviews.llvm.org/D43886 and extends LLDB support of Obj-C exceptions to also look for a "current exception" for a thread in the C++ exception handling runtime metadata (via call to __cxa_current_exception_type). We also construct an actual historical SBThread/ThreadSP that contains frames from the backtrace in the Obj-C exception object.

The high level goal this achieves is that when we're already crashed (because an unhandled exception occurred), we can still access the exception object and retrieve the backtrace from the throw point. In Obj-C, this is particularly useful because a catch+rethrow is very common and in those cases you currently don't have any access to the throw point backtrace.

e60bc53b46 [lldb] Add GetCurrentException APIs to SBThread, add frame recognizer for objc_exception_throw for Obj-C runtimes
This adds new APIs and a command to deal with exceptions (mostly Obj-C exceptions): SBThread and Thread get GetCurrentException API, which returns an SBValue/ValueObjectSP with the current exception for a thread. "Current" means an exception that is currently being thrown, caught or otherwise processed. In this patch, we only know about the exception when in objc_exception_throw, but subsequent patches will expand this (and add GetCurrentExceptionBacktrace, which will return an SBThread/ThreadSP containing a historical thread backtrace retrieved from the exception object. Currently unimplemented, subsequent patches will implement this).

Extracting the exception from objc_exception_throw is implemented by adding a frame recognizer.

This also add a new sub-command "thread exception", which prints the current exception.

eca07c592a Fix (and improve) the support for C99 variable length array types
Clang recently improved its DWARF support for C VLA types. The DWARF
now looks like this:

0x00000051:         DW_TAG_variable [4]
                     DW_AT_location( fbreg -32 )
                     DW_AT_name( "__vla_expr" )
                     DW_AT_type( {0x000000d3} ( long unsigned int ) )
                     DW_AT_artificial( true )
...
0x000000da:     DW_TAG_array_type [10] *
                 DW_AT_type( {0x000000cc} ( int ) )

0x000000df:         DW_TAG_subrange_type [11]
                     DW_AT_type( {0x000000e9} ( __ARRAY_SIZE_TYPE__ ) )
                     DW_AT_count( {0x00000051} )

Without this patch LLDB will naively interpret the DIE offset 0x51 as
the static size of the array, which is clearly wrong.  This patch
extends ValueObject::GetNumChildren to query the dynamic properties of
incomplete array types.

See the testcase for an example:

   4   int foo(int a) {
   5   	     int vla[a];
   6   	       for (int i = 0; i < a; ++i)
   7   	           vla[i] = i;
   8
-> 9            pause(); // break here
   10  		return vla[a-1];
   11   }

(lldb) fr v vla
(int []) vla = ([0] = 0, [1] = 1, [2] = 2, [3] = 3)
(lldb) quit

The plugin can be added again in the future if it is mature enough both

bf2d112c15 [DWARFExpression] Read literars as unsigned values.
After landing r341457, we started seeing a failure on the swift-lldb
bots. The change was correct and pretty straightforward, a DW_OP_constu
was replaced with DW_OP_lit23, the value remaining identical.

  0x000000f4: DW_TAG_variable
		DW_AT_location    (0x00000000
		  [0x0000000100000a51,  0x0000000100000d47): DW_OP_lit23, DW_OP_stack_value)
		DW_AT_name        ("number")

However, this broke LLDB.

  (Int) number = <extracting data from value failed>

The value was read correctly, but apparently the value's type was different.
When reading a constu it was reading a uint64 (m_type = e_ulonglong) while for
the literal, it got a signed int (m_type = e_sint). This change makes sure we
read the value as an unsigned.

ae6ca2fc3f Allow IRInterpreter to deal with non-power-of-2 sized types to support some bitfield accesses.
Summary:
For some bitfield patterns (like the one added by this commit), Clang will
generate non-regular data types like i24 or i48. This patch follows a
pretty naive approach of just bumping the type size to the next power of 2.
DataExtractor know how to deal with weird sizes. The operations on Scalar
do not know how to deal with those types though, so we have to legalize the
size when creating a Scalar.
