John Stiles 55dc5c8325 Fix assertion in constant-folder when using float4(mat2) casts.
The no-op-arithmetic simplifier was written before we allowed casting a
mat2x2 to a float4, and did not expect a matrix inside a vector ctor.
The expression `float4(myMat2) * float4(anything)` would assert when we
tried to determine if `myMat2` was a constant zero or constant one.

The code has been rewritten to use getConstantSubexpression and now
allows matrices inside.
