f553db2d30 HalfFloatPlane unittest for denormal half floats 
Halffloats have a limited range.  It shouldnt normally come up, but if the scale value passed in produces a small value, the half floats will be denormals, which are slow and/or flust to zero.  This test ensures they behave the same in C and SIMD and tests the performance of denormals.

As clangcl mimics both Visual C and GCC, ifdefs need to pick one or the other or often you'll end up with both. In this CL we disable most Visual C code and use the GCC versions which allow assembly for both 32 and 64 bit intel.
