[Bug tree-optimization/18587] build_v_may_defs and build_vuses should be hastables instead of varray

I have no idea what you are talking about.  what are you doing, adding a hash
value to the stmt for the vmaydef and vuse lists?

And in the new numbers, why does tree alaising go down if its not affected? And
btw, it goes down in time, but increases from 6% of compile time to 14%? and at
the same time the operand scan goes from 26 sec. or 7% of compile time down to
14sec. but now comsumes 9% of compile time?

something doesnt add up. are you mixing enable checking and disabled checking
compiles?
