Replace some unsafe API calls with safe alternatives on Windows, prepare code for similar actions on other platforms - wrap unsafe API calls into macros.

Eliminated the write to depth field of the machine_hierarchy data structure in __kmp_get_hierarchy(), thus fixing race condition. Now local variable used by each thread.

MSVC 2013 can't even parse __declspec(align(sizeof(foo))). We'll have to
wait until MSVC 2015 for this.

This partially reverts commit r233911.

This isn't perfect as it still assumes sizeof(void*) == alignof(void*),
but we can fix that when compiler support gets better.

Shrinks some Stmts that happen to inherit from Stmt and have a
SourceLocation as the first member (64 bit archs only).

llvm-svn: 233911

We wrap __attribute((aligned)) for GCC 4.7 and __declspec(align) for
MSVC. The latter behaves weird in some contexts so this should be used
carefully.

Summary:
Avoid duplicate code in Mips16FrameLowering and MipsSEFrameLowering by
providing an implementation of the eliminateCallFramePseudoInstr()
function from their base class.

Depends on D8640.

These test cases check if they are able to read registers after the
inferior is crashed. Previously they did it with reading the eax
register what is only available on i386 and x86_64. Thic CL add code to
do the check based on the target architecture (currently i386, x86_64
and aarch64 is supported)

Summary:
adjustStackPtr() is implemented from both MipsSEInstrInfo and
Mips16InstrInfo. It makes sense to expose this function from
MipsInstrInfo and avoid explicit casting in some cases.

Depends on D8638.

Since we no longer support MSVC 2012, we can assume that variadic
templates are always supported. This patch removes an #ifdef for
C++ compilers that don't support variadic templates.

The function call that goes through PLT table may be performed
from both ARM and Thumb code.
This situation requires adding a veneer to original PLT code
(which is always ARM) to effect Thumb-to-ARM transition.

There is one-to-one correspondence between ELF machine type and a
LinkingContext. We passed them as separate arguments to the constructor.
This patch is to teach the LinkingContexts about their machine types,
so that we don't need to pass that data as separate arguments.

These two were never implemented for gcroot, so there's no point in keeping them around now.

I'm playing with supporting custom stack map formats with statepoints.  While 
doing so, I noticed that the existing implementation didn't indicate inherently 
unsized frames.  This change essentially just ports the functionality that already 
exists for the default StackMaps section to custom stackmaps.

Swapping DenseMap A with DenseMap B invalidates iterators pointing into

Nothing is using DenseMapBase::swap.  Besides it does not compile in its

MipsRuntimeFile doesn't seem to add values to the base class,

registerRelocationNames() function is called to register all known
ELF relocation types to the central registry. Since we have separate
LinkingContext class for each ELF machine type, we need to call the
function for each LinkingContext.

However, the function belonged to TargetHandler instead of LinkingContext.
So we needed to do ctx.getTargetHandler().registerRelocationNames().
This patch removes that redundant getTargetHandler call by moving the
function from TargetHandler to LinkingContext.

Conceptually this patch is small, but in reality it's not that small.
It's because the same code is copied to each architecture.
Most of this patch is just repetition. We need to merge them, but
that cannot be done in this patch.

llvm-svn: 233883

Also removed some over-generalization added in r232866, such as
making a function take two parameters and pass two equivalent
arguments to the function.

This uses the same class metadata currently used for virtual call and

The new flag is -fsanitize=cfi-nvcall. For consistency, the -fsanitize=cfi-vptr
