Hi Jay, This commit creates a very weird problem on MSVC where clang
test /CodeGen/vla.c stalls in release mode. (but not in debug).

I suspect a subtle memory corruption issue that doesn't show up on the
various unixes system because we get lucky. Windows .exe are generally
easier to crash if there is a memory corruption issue.

Thank to chapuni for identifying this commit as the source of the problem.
