[TargetLowering] Add support for non-uniform vectors to BuildSDIV

This patch refactors the existing TargetLowering::BuildSDIV base implementation to support 
non-uniform constant vector denominators.

This is the last patch necessary to close PR36545

[codeview] Use push_macro to avoid conflicts instead of a prefix

Summary:
This prefix was added in r333421, and it changed our dumper output to
say things like "CVRegEAX" instead of just "EAX". That's a functional
change that I'd rather avoid.

I tested GCC, Clang, and MSVC, and all of them support #pragma
push_macro. They don't issue warnings whem the macro is not defined
either.

I don't have a Mac so I can't test the real termios.h header, but I
looked at the termios.h sources online and looked for other conflicts.
I saw only the CR* macros, so those are the ones we work around.

[MS Demangler] Demangle string literals.

When demangling string literals, Microsoft's undname
simply prints 'string'.  This patch implements string
literal demangling while doing a bit better than this
by decoding as much of the string as possible and
trying to faithfully reproduce the original string
literal definition.

This is a bit tricky because the different character
types char, char16_t, and char32_t are not uniquely
identified by the mangling, so we have to use a
heuristic to try to guess the character type.  But
it works pretty well, and many tests are added to
illustrate the behavior.

LLVM — llvm/trunk/utils/TableGen CodeGenDAGPatterns.cpp

[TableGen] TypeSetByHwMode::operator== optimization

This operator is called a great deal, by checking for the cheap isSimple equality cases 
first (a common occurrence) we can improve performance as we avoid a lot of std::map 
find/iteration in hasDefault.

isSimple also means that a default value is present, so we can avoid some hasDefault 
calls.

This also avoids a rather dodgy piece of logic that was checking for isSimple() && 
!VTS.isSimple() but not the inverse - it now uses the general hasDefault mode comparison 
test instead.

[libcxx] By default, do not use internal_linkage to hide symbols from the ABI

Summary:
https://reviews.llvm.org/D49240 led to symbol size problems in Chromium, and
we expect this may be the case in other projects built in debug mode too.
Instead, unless users explicitly ask for internal_linkage, we use always_inline
like we used to.

In the future, when we have a solution that allows us to drop always_inline
without falling back on internal_linkage, we can replace always_inline by
that.

Note that this commit introduces a change in contract for existing libc++
users: by default, libc++ used to guarantee that TUs built with different
versions of libc++ could be linked together. With the introduction of the
_LIBCPP_HIDE_FROM_ABI_PER_TU macro, the default behavior is that TUs built
with different libc++ versions are not guaranteed to link. This is a change
in contract but not a change in behavior, since the current implementation
still allows linking TUs built with different libc++ versions together.

[RISCV][MC] Don't fold symbol differences if requiresDiffExpressionRelocations is true

When emitting the difference between two symbols, the standard behavior is 
that the difference will be resolved to an absolute value if both of the 
symbols are offsets from the same data fragment. This is undesirable on 
architectures such as RISC-V where relaxation in the linker may cause the 
computed difference to become invalid. This caused an issue when compiling to 
object code, where the size of a function in the debug information was already 
calculated even though it could change as a consequence of relaxation in the 
subsequent linking stage.

This patch inhibits the resolution of symbol differences to absolute values 
where the target's AsmBackend has declared that it does not want these to be 
folded.

The TagDecl *OwnedTagDecl in ElaboratedType is quite commonly

common case by storing it as a trailing object, and storing a bit in the
bit-fields of Type indicating when the pointer is null.

[PowerPC] Don't run BV DAG Combine before legalization if it assumes legal types

When trying to combine a DAG that builds a vector out of sign-extensions of
vector extracts, the code assumes legal input types. Due to that, we have to
disable this combine prior to legalization.
In some cases, the DAG will look slightly different after legalization so
account for that in the matching code.

[ARM] Allow signed icmps in ARMCodeGenPrepare
    
Originally committed in r339755 which was reverted in r339806 due to
an asan issue. The issue was caused by my assumption that operands to

handled by iterating over their ArgOperands instead of Operands.
    
Original Message:
  Treat signed icmps as 'sinks', allowing them to be in the use-def
  tree, enabling more promotions to be performed. As a sink, any
  promoted incoming values need to be truncated before being used by
  the signed icmp.
