Jakob Stoklund Olesen bde32d36bb Make X86::FsFLD0SS / FsFLD0SD real pseudo-instructions.
Like V_SET0, these instructions are expanded by ExpandPostRA to xorps /
vxorps so they can participate in execution domain swizzling.

This also makes the AVX variants redundant.

Mon P Wang 88ff56caa3 Make isScalarToVector to return false if the node is a scalar. This will prevent
DAGCombine from making an illegal transformation of bitcast of a scalar to a
vector into a scalar_to_vector.
