Always inlining PrintCurrentStackSlow of tsan library to fix tail-call issue
The real problem is that sanitizer_print_stack_trace obtains current PC and
expects the PC to be in the stack trace after function calls. We don't
prevent tail calls in sanitizer runtimes, so this assumption does not
necessary hold.
We add "always inline" attribute on PrintCurrentStackSlow to address this
issue, however this solution is not reliable enough, but unfortunately, we
don't see any simple, reliable solution.

[libcxx] Fix PR15638 - Only allocate in parent when starting a thread to prevent calling terminate.
Summary:
Hi,
When creating a new thread libc++ performs at least 2 allocations. The first allocates a tuple of args and the functor that will be passed to the new thread. The second allocation is for the thread local storage needed internally by libc++. Currently the second allocation happens in the child thread, meaning that if it throws the program will terminate with an uncaught bad alloc.
The solution to this is to allocate ALL memory in the parent thread and then pass it to the child.

[ARM NEON] Define vfms_f32 on ARM, and all vfms using vfma.
r259537 added vfma/vfms to armv7, but the builtin was only lowered
on the AArch64 side. Instead of supporting it on ARM, get rid of it.
The vfms builtin lowered to:
%nb = fsub float -0.0, %b
%r = @llvm.fma.f32(%a, %nb, %c)
Instead, define the operation in terms of vfma, and swap the
multiplicands. It now lowers to:
%na = fsub float -0.0, %a
%r = @llvm.fma.f32(%na, %b, %c)
This matches the instruction more closely, and lets current LLVM
generate the "natural" operand ordering:
fmls.2s v0, v1, v2
instead of the crooked (but equivalent):
fmls.2s v0, v2, v1
Except for theses changes, assembly is identical.
LLVM accepts both commutations, and the LLVM tests in:
test/CodeGen/AArch64/arm64-fmadd.ll
test/CodeGen/AArch64/fp-dp3.ll
test/CodeGen/AArch64/neon-fma.ll
test/CodeGen/ARM/fusedMAC.ll
already check either the new one only, or both.
Also verified against the test-suite unittests.

[SSP, 2/2] Create llvm.stackguard() intrinsic and lower it to LOAD_STACK_GUARD
With this change, ideally IR pass can always generate llvm.stackguard
call to get the stack guard; but for now there are still IR form stack
guard customizations around (see getIRStackGuard()). Future SSP
customization should go through LOAD_STACK_GUARD.
There is a behavior change: stack guard values are not CSEed anymore,
since we should never reuse the value in case that it has been spilled (and
corrupted). See ssp-guard-spill.ll. This also cause the change of stack
size and codegen in X86 and AArch64 test cases.
Ideally we'd like to know if the guard created in llvm.stackprotector() gets
spilled or not. If the value is spilled, discard the value and reload
stack guard; otherwise reuse the value. This can be done by teaching
register allocator to know how to rematerialize LOAD_STACK_GUARD and
force a rematerialization (which seems hard), or check for spilling in
expandPostRAPseudo. It only makes sense when the stack guard is a global
variable, which requires more instructions to load. Anyway, this seems to go out
of the scope of the current patch.

IR: Enable debug info type ODR uniquing for forward decls
Add a new method, DICompositeType::buildODRType, that will create or
mutate the DICompositeType for a given ODR identifier, and use it in
LLParser and BitcodeReader instead of DICompositeType::getODRType.
The logic is as follows:
- If there's no node, create one with the given arguments.
- Else, if the current node is a forward declaration and the new
arguments would create a definition, mutate the node to match the
new arguments.
- Else, return the old node.
This adds a missing feature supported by the current DITypeIdentifierMap
(which I'm slowly making redudant). The only remaining difference is
that the DITypeIdentifierMap has a "the-last-one-wins" rule, whereas
DICompositeType::buildODRType has a "the-first-one-wins" rule.
For now I'm leaving behind DICompositeType::getODRType since it has
obvious, low-level semantics that are convenient for unit testing.
