John Stiles 9ae6ea0711 Fix fuzzer-discovered error with swizzling matrices.
The optimization logic for swizzling a constructor assumed that every
argument to the constructor was a scalar or vector. When it was written,
this assumption was true. However, we recently added support for casting
mat2x2 to float4 which violates the assumption.

We now check every argument and do not attempt to optimize if a
non-scalar, non-vector arg is found.
