[X86] Rename the VEX scalar fma builtins to end with a '3' to match gcc

I think we need to use different builtins for the FMA4 instructions since those instructions zero the upper bits and FMA3 instructions pass the bits through.

So this moves the existing builtins to be the FMA3 versions. New versions will be added for FMA4.
