Reid Kleckner 7510c09234 Fix data layout mismatch between LLVM and Clang for i686-pc-windows-msvc-elf
Do the same thing as win64. If we're not using COFF, use the ELF
manglings. Maybe if we are targetting *-windows-msvc-macho, we should
use darwin manglings, but I don't need to stir that pot today.

Reid Kleckner 80944df6f4 Implement IRGen for the x86 vectorcall convention
The most complex aspect of the convention is the handling of homogeneous
vector and floating point aggregates.  Reuse the homogeneous aggregate
classification code that we use on PPC64 and ARM for this.

This convention also has a C mangling, and we apparently implement that
in both Clang and LLVM.

Nico Weber 8f63ae1d4c Simplify tests.
This reverts bits of r218166 that are no longer necessary now that r218394 made
-Wmissing-prototype-for-cc a regular warning.

Nico Weber d191063c6c Follow-up to r214408: Warn on other callee-cleanup functions without prototype too.
According to lore, we used to verifier-fail on:

  void __thiscall f();
  int main() { f(1); }

So that's fixed now. System headers use prototype-less __stdcall functions,
so make that a warning that's DefaultError -- then it fires on regular code
but is suppressed in system headers.

Since it's used in system headers, we have codegen tests for this; massage
them slightly so that they still compile.

Hans Wennborg c9bd88e681 Remove the -cxx-abi command-line flag.
This makes the C++ ABI depend entirely on the target: MS ABI for -win32 triples,
Itanium otherwise. It's no longer possible to do weird combinations.

To be able to run a test with a specific ABI without constraining it to a
specific triple, new substitutions are added to lit: %itanium_abi_triple and
%ms_abi_triple can be used to get the current target triple adjusted to the
desired ABI. For example, if the test suite is running with the i686-pc-win32
target, %itanium_abi_triple will expand to i686-pc-mingw32.

Rafael Espindola 002667c32b On 32 bit windows, mangle stdcall and fastcall decls in clang.
This removes the dependency on the llvm mangler doing it for us. In isolation,
the benefit is that the testing of what mangling is applied is all in one place:
(C, C++) X (Itanium, Microsoft) are all handled by clang.

This also gives me hope that in the future the llvm mangler (and llvm-ar) will
not depend on TargetMachine.
