Matt Arsenault 539412914a GlobalISel: Use LibcallLoweringInfo analysis in legalizer (#170328) ...

This is mostly boilerplate to move various freestanding utility
functions into LegalizerHelper. LibcallLoweringInfo is currently
optional, mostly because threading it through assorted other
uses of LegalizerHelper is more difficult.

I had a lot of trouble getting this to work in the legacy pass
manager with setRequiresCodeGenSCCOrder, and am not happy with the
result. A sub-pass manager is introduced and this is invalidated,
so we're re-computing this unnecessarily.
