[PATCH] D1623: Support __builtin_ms_va_list.

[Charles Davis via cfe-commits]

cdavis5x updated this revision to Diff 34415.
cdavis5x added a comment.

- Rebase onto http://reviews.llvm.org/rL247238.
- Run `clang-format` on this patch.
- Push `va_arg` emission down into the `ABIInfo` hierarchy.

I threaded the `IsMS` parameter from the `VAArgExpr` through the
`EmitVAArg` methods. I'm not entirely happy about this design; I'm open
to suggestions. One thing this does help, though, is supporting this
on other architectures (ARM, maybe?).
