[PATCH] D86508: [clang] improve GCC-compat for C90 __builtin_ functions

[Richard Smith - zygoloid via Phabricator via cfe-commits]

rsmith added a comment.

It seems to me that adding new `__builtin_*` functions for GCC compatibility and adding new `LIBBUILTIN`s are unrelated changes, and it might be clearer to split them up into two commits.
