John Stiles cfa9938936 Simplify -1 * x into -x. 
We already performed a matching simplification for `0 - x`, so this
seemed like a straightforward improvement.

Performing this simplification causes the expressions in the test code
to match on both sides (e.g. `-one == -one`) which allows them to fold
away.
