__cxa_atexit call that would normally cause these

errors of the form

baby steps toward fixing some problems with inbound GEPs that overflow, as discussed 2 months ago or so.
Make sure we do not emit index computations with NSW flags so that we dont get an undef value if the GEP overflows

move the bounds checking pass to the instrumentation folder, where it belongs. I dunno why in the world I dropped it in the Scalar folder in the first place.

Under AAPCS, long double is the same as double, which means it should be
allowed as part of a homogeneous aggregate.

Add "vAttachOrWait" to debugserver, so you can implement "attach to the process if it exists OR wait for it" without race conditions.  Use that in lldb.

For testing, c-index-test now has even more output:

* comment AST tree dump in S-expressions like Comment::dump(), but implemented
* with libclang APIs.

LiveRangeEdit::foldAsLoad() can eliminate a register by folding a load
into its only use. Only do that when the load is safe to move, and it
won't extend any live ranges.

This fixes PR13414.

assembly.  

By default, we don't emit IR for MS-style inline assembly (see r158833 as to 
why).  This is strictly for testing purposes and should not be enabled with the
expectation that things will work.  This is a temporary flag and will be removed
once MS-style inline assembly is fully supported.

CI's name, and then used the StringRef pointing at its old name. I'm
fixing it by storing the name in a std::string, and hoisting the
renaming logic to happen always. This is nicer anyways as it will allow
the upgraded IR to have the same names as the input IR in more cases.

Another bug found by AddressSanitizer. Woot.

PHIElimination splits critical edges when it predicts it can resolve
interference and eliminate copies. It doesn't split the edge if the
interference wouldn't be resolved anyway because the phi-use register is
live in the critical edge anyway.

Teach PHIElimination to split loop exiting edges with interference, even
if it wouldn't resolve the interference. This removes the necessary
copies from the loop, which is still an improvement from injecting the
copies into the loop.

The test case demonstrates the improvement. Before:

LBB0_1:
  cmpb  $0, (%rdx)
  leaq  1(%rdx), %rdx
  movl  %esi, %eax
  je  LBB0_1

After:

LBB0_1:
  cmpb  $0, (%rdx)
  leaq  1(%rdx), %rdx
  je  LBB0_1

  movl  %esi, %eax

No longer assuming the number of prototype arguments is always less than the number of formal parameters for a variadic function call.

The assertion was wrong in case we have a verbatim block without a closing
command.

Also add tests for closing command name in a verbatim block, since now it can
be empty in such cases.

since they don't have a valid column width, and they don't look good anyway.
