[PPC64] VSX indexed-form loads use wrong instruction format
The VSX instruction definitions for lxsdx, lxvd2x, lxvdsx, and lxvw4x
incorrectly use the XForm_1 instruction format, rather than the
XX1Form instruction format. This is likely a pasto when creating
these instructions, which were based on lvx and so forth. This patch
uses the correct format.
The existing reformatting test (test/MC/PowerPC/vsx.s) missed this
because the two formats differ only in that XX1Form has an extension
to the target register field in bit 31. The tests for these
instructions used a target register of 7, so the default of 0 in bit
31 for XForm_1 didn't expose a problem. For register numbers 32-63
this would be noticeable. I've changed the test to use higher
register numbers to verify my change is effective.

Push DwarfDebug::constructScopeDIE down into DwarfCompileUnit
One of many steps to generalize subprogram emission to both the DWO and
non-DWO sections (to emit -gmlt-like data under fission). Once the
functions are pushed down into DwarfCompileUnit some of the data
structures will be pushed at least into DwarfFile so that they can be
unique per-file, allowing emission to both files independently.

Update dwarf::ApplePropertyAttributes enum to meaningful values.
Summary:
We currently emit an DW_AT_APPLE_property_attribute with a value that is a
bitfield describing the various attributes applied to an ObjectiveC property.
While trying to add testing to one of my dwarfdump patches that would pretty
print that, I realized this information looks totally broken and has maybe
never been correct.
As with every DWARF info, we have some enum in Dwarf.h that describes this
attribute (enum ApplePropertyAttributes). It seems however that the attribute
value is set from another definition of these flags in Sema/DeclSpec.h (enum
ObjCPropertyAttributeKind). And these 2 enums aren't in sync.
This patch updates the Dwarf.h values to the ones we are (and have been for
a very long time) emitting. We change some publicly (and even documented
in SourceLevelDebugging.rst) values, but I doubt this could be an issue as
the information has been wrong for so long...

[X86] Fix a bug with fetch_add(INT32_MIN)
Summary:
Fix pr21099
The pseudocode of what we were doing (spread through two functions) was:
if (operand.doesNotFitIn32Bits())
Opc.initializeWithFoo();
if (operand < 0)
operand = -operand;
if (operand.doesFitIn8Bits())
Opc.initializeWithBar();
else if (operand.doesFitIn32Bits())
Opc.initializeWithBlah();
doStuff(Opc);
So for operand == INT32_MIN, Opc was never initialized because the operand changes
from fitting in 32 bits to not fitting, causing the various bugs/error messages
noted by pr21099.
This patch adds an extra test at the beginning for this case, and an
llvm_unreachable to have better error message if the operand ends up
not fitting in 32-bits at the end.

DebugInfo+DFSan: Ensure that debug info references to llvm::Functions remain pointing to the underlying function when wrappers are created
This is somewhat the inverse of how similar bugs in DAE and ArgPromo
manifested and were addressed. In those passes, individual call sites
were visited explicitly, and then the old function was deleted. This
left the debug info with a null llvm::Function* that needed to be
updated to point to the new function.
In the case of DFSan, it RAUWs the old function with the wrapper, which
includes debug info. So now the debug info refers to the wrapper, which
doesn't actually have any instructions with debug info in it, so it is
ignored entirely - resulting in a DW_TAG_subprogram with no high/low pc,
etc. Instead, fix up the debug info to refer to the original function
after the RAUW messed it up.
Reviewed/discussed with Peter Collingbourne on the llvm-dev mailing
list.

[Bugpoint] Close error log in ProcessFailure. Bugpoint had been failing to close
this, and in some circumstances (e.g. reducing particularly large test-cases)
this was causing bugpoint to be killed for hitting open file-handle limits.
No test case: I was only able to trigger this with test cases taking upwards of
10 mins to run.
