[PowerPC] Implement vector bool/pixel initialization under -faltivec-src-compat=xl
This patch implements the initialization of vectors under the
-faltivec-src-compat=xl option introduced in https://reviews.llvm.org/D103615.
Under this option, the initialization of scalar vectors, vector bool, and vector
pixel are treated the same, where the initialization value is splatted across
the whole vector.
This patch does not change the behaviour of the -faltivec-src-compat=mixed option,
which is the current default for Clang.

[InstrRef][X86] Drop debug instruction numbers from x87 instructions
Avoid a crash when using instruction referencing if x87 floating point
instructions are used. These instructions are significantly mutated when
they're rewritten from referring to registers, to referring to
floating-point-stack positions. As a result, their operands are re-ordered,
and (InstrRef) LiveDebugValues asserts when it sees a DBG_INSTR_REF
referring to a non-reg non-def register operand.
To fix this, drop the instruction numbers, and thus variable locations.
This patch adds a helper utility do do that.
Dropping the variable locations is sub-optimal, but applying DBG_VALUEs to
the $fp0 and similar registers is dropped on emission too. It seems we've
never done well at describing variables that live in x87 registers, at all.

thread_local support for AIX
Summary:
The AIX linker will produce errors on unresolved weak symbols. Change the
generated code to not check for the initialization function but just call
it and ensure that it always exists. Also, the AIX atexit routine has a
different name (and signature) so call it correctly. Update the lit tests
to test on AIX appropriately.

This is part of a patch series working towards the ability to make

tsan: make obtaining current PC faster
We obtain the current PC is all interceptors and collectively
common interceptor code contributes to overall slowdown
(in particular cheaper str/mem* functions).
The current way to obtain the current PC involves:
4493e1: e8 3a f3 fe ff callq 438720 <_ZN11__sanitizer10StackTrace12GetCurrentPcEv>
4493e9: 48 89 c6 mov %rax,%rsi

uptr StackTrace::GetCurrentPc() {
438720: 48 8b 04 24 mov (%rsp),%rax
438724: c3 retq
The new way uses address of a local label and involves just:
44a888: 48 8d 35 fa ff ff ff lea -0x6(%rip),%rsi
I am not switching all uses of StackTrace::GetCurrentPc to GET_CURRENT_PC
because it may lead some differences in produced reports and break tests.
The difference comes from the fact that currently we have PC pointing
to the CALL instruction, but the new way does not yield any code on its own
so the PC points to a random instruction in the function and symbolizing
that instruction can produce additional inlined frames (if the random
instruction happen to relate to some inlined function).
