RegScavenger::unprocess walks backward, so it should undo the effects
of defs before undoing effects of kills. Previously it did things in
the opposite order, leaving a register apparently unused (dead) in the
case where an instruction both used (killed) and defined a register.

If QMM_Result is set (which it is for return types, RTTI descriptors, and
exception type descriptors), tag types (structs, enums, classes, unions) get
their qualifiers mangled in.

__m64 and friends is a struct/union thingy in MSVC, but not in clang's headers.
To make mangling work, we call mangleArtificalTagType(TTK_Union/TTK_Struct for
the vector types to mangle them as tag types -- but the isa<TagType> check when
mangling in QMM_Result mode isn't true for these vector types. Add an
isArtificialTagType() function and check for that too. Fixes PR37276 and some
other issues.

I tried to audit all references to TagDecl and TagType in MicrosoftMangle.cpp
to find other places where we need to call mangleArtificalTagType(), but
couldn't find any.

I tried to audit all calls to mangleArtificalTagType() to see if
isArtificialTagType() needs to handle more than just the vector types, but as
far as I can tell all other types we use it for are types that MSVC can't
handle at all (Objective-C types etc).

The gold behaviour with regard to --keep-unique is arguably a bug.
I also noticed a bug in my patch, which is that we mislink the
following program with --icf=safe by merging f3 and f4:

void f1() {}
void f2() {}

__attribute__((weak)) void* f3() { return f1; }
__attribute__((weak)) void* f4() { return f2; }

int main() {
  printf("%p %p\n", f3(), f4());
}

No functionality change intended: I don't believe any of the diagnostics
affected by this patch are reachable when initializing the result of

Dynamic section holds a table, so the sh_entsize might be set. As the

Currently, support for debug_types is only present for ELF and trying to

In preparing to allow ARMParallelDSP pass to parallelise more than
smlads, I've restructed some elements:

- The ParallelMAC struct has been renamed to BinOpChain.
- The BinOpChain struct holds two value lists: LHS and RHS, as well
  as inheriting from the OpChain base class.
- The OpChain struct holds all the values of the represented chain
  and has had the memory locations functionality inserted into it.
- ParallelMACList becomes OpChainList and it now holds pointers
  instead of objects.
