Soliciting Code Review: Fix for Bug 5053

Bug: [windows JIT] incorrect ‘frem’ behavior with floats (http://llvm.org/bugs/show_bug.cgi?id=5053)

Patch for review: http://reviews.llvm.org/D5387

This patch fixes an LLI.exe crash on Windows\X86 when certain single precession floating point intrinsics are used.

I’d appreciate if one of you could review the patch.

Thanks,

Swaroop.
