[PATCH] D104830: AST: Create __va_list in the std namespace even in C.

Herald added a project: clang.

This ensures that the mangled type names match between C and C++,
which is significant when using -fsanitize=cfi-icall. Ideally we
wouldn't have created this namespace at all, but it's now part of
the ABI (e.g. in mangled names), so we can't change it.
