Josh Bleecher Snyder 01b1a34aac cmd/compile: rework handling of udiv on ARM 
Instead of populating the aux symbol
of CALLudiv during rewrite rules,
populate it during genssa.

This simplifies the rewrite rules.
It also removes all remaining calls
to ctxt.Lookup from any rewrite rules.
This is a first step towards removing
ctxt from ssa.Cache entirely,
and also a first step towards converting
the obj.LSym.Version field into a boolean.
It should also speed up compilation.

Also, move func udiv into package runtime.
That's where it is anyway,
and it lets udiv look and act like the rest of
the runtime support functions.
