The scalar float/double function bodies are a direct copy/paste
with usage of the CLC wrappers to vectorize them.
This commit also adds in the FP_ILOGB0 and FP_ILOGBNAN macros which are
equal to the results of ilogb(0.0f) and ilogb(float nan) respectively.
v2: Add FP_ILOGB0 and FP_ILOGBNAN definitions
