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.
