There is currently no support in MSVC for using i128 as an integer
literal suffix. In fact, there appears to be no evidence that they have
ever supported this feature in any of their compilers. This was an over
generalization of their actual feature and is a nasty source of bugs.
Why is it a source of bugs? Because most code in clang expects that
evaluation of an integer constant expression won't give them something
that 'long long' can't represent. Instead of providing a meaningful
feature, i128 gives us cute ways of exploding the compiler.

We would make i8 literals turn into signed char instead of char. This
is incompatible with MSVC.
This fixes PR22824.

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.

This reverts commit r211426.
This broke the arm bots. The crash can be reproduced on X86 by running.
./bin/clang -cc1 -fsyntax-only -verify -fms-extensions ~/llvm/clang/test/Lexer/ms-extensions.c -triple arm-linux
