John Stiles 71624de2c5 Allow constant propagation for negated constant-vectors and ints. ... This CL improves on the previous fix for oss-fuzz:26789 by actually propagating the negation from the PrefixExpression inside the constructor, which unblocks further optimizations. Interestingly, this fix also exposes a further missing optimization--we optimize away comparisons of constant-vectors for floats, but fail to do the same for ints.
