John Stiles f89a8122a4 Fix flaws in minus-prefix optimization. 
We had a logic bug when attempting to optimize the following code:
    const vecN x = vecN(a, b, c);
    -x;

The goal was to replace `-x` with `vecN(-a, -b, -c)` but we accidentally
tried to cast the `x` VariableReference to a Constructor. We
unfortunately didn't cover this in any of our test cases, but the fuzzer
managed to synthesize it by mixing and matching elements from its new
corpus.

This affected several different constructor types: splat, diagonal-
matrix, compound and array.
