MS ABI: Properly call global delete when invoking virtual destructors

Summary:
The Itanium ABI approach of using offset-to-top isn't possible with the
MS ABI, it doesn't have that kind of information lying around.

Instead, we do the following:
- Call the virtual deleting destructor with the "don't delete the object
  flag" set.  The virtual deleting destructor will return a pointer to
  'this' adjusted to the most derived class.
- Call the global delete using the adjusted 'this' pointer.

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.

Silence a warning from MSVC "14" by making an enum unsigned

It says there is a narrowing conversion when we assign it to an unsigned
3 bit bitfield.

Also, use unsigned instead of size_t for the Size field of the struct in
question. Otherwise they won't run together in MSVC or clang-cl.
