[PATCH] D121497: Lex: add support for `{,u}i128` Microsoft extension

compnerd added a comment.

This was something that I was hitting an issue with.  In particular, it was a module build for a module which pulled in intsafe.h.  Now, given that it is a preprocessor macro, it would stand to reason that it will normally be dropped and thus won't matter if the frontend doesn't actually support a 128-bit type.  However, with a module, we would attempt to process the expression.  I do admit it is on a slightly more tenuous ground as Microsoft may somehow do something different.
