Lex: Use the correct types for MS integer suffixes Something went wrong with r211426, it is an older version of this code and should not have been committed. It was reverted with r211434. Original commit message: We didn't properly implement support for the sized integer suffixes. Suffixes like i16 were essentially ignored instead of mapping them to the appropriately sized integer type. This fixes PR20008. Differential Revision: http://reviews.llvm.org/D4132 llvm-svn: 211441

Sema: The i8 suffix should yield a literal of type char We would make i8 literals turn into signed char instead of char. This is incompatible with MSVC. This fixes PR22824. llvm-svn: 231494
