[X86] Use masked the masked scalar fma builtins to implement the default rounding version of the fma intrinsics.

The rounding mode is checked in CGBuiltin.cpp to generate the correct intrinsic call.

Making this switch switchs the masking to use the i8 bitcast to <8 x i1> and extract i1 version of the IR for the mask. Previously we ended up with a scalar 'and' plus an icmp.
