graphene-simd4f.h: Fix MSVC Defines for Intrinistics

... from commit 9b0b22c (simd4f: Add more comparison operators), as the
MSVC initrinics calls were not correct (i.e. they should be in-sync with
the GCC ones, and a function name was off, which broke the build and the
tests.  Fix that.

p.s. The code in its current state is only buildable with Visual Studio
2013 for Visual Studio.
