Log:
Add a define_simplification construct
[Branch only patch -- not intended for trunk in its current state]
This patch adds a way for targets to define their own simplification
rules and uses it to optimise vector selects for SVE.
I thought at one point we might use this more often, but we never did.
It's debatable whether it's worth submitting for trunk for just this
one case.
