      cmd/compile: canonicalize empty interface types · 62947bed
      Josh Bleecher Snyder authored 
      Mapping all empty interfaces onto the same Type
allows better reuse of the ptrTo and sliceOf
Type caches for *interface{} and []interface{}.

This has little compiler performance impact now,
but it will be helpful in the future,
when we will eagerly populate some of those caches.

Passes toolstash-check.

      cmd/compile: add more types to ssa.Types · 872db799
      Josh Bleecher Snyder authored 
      This reduces the number of calls back into the
gc Type routines, which will help performance
in a concurrent backend.
It also reduces the number of callsites
that must be considered in making the transition.

Passes toolstash-check -all. No compiler performance changes.

      cmd/compile: separate ssa.Frontend and ssa.TypeSource · aea3aff6
      Josh Bleecher Snyder authored 
      Prior to this CL, the ssa.Frontend field was responsible
for providing types to the backend during compilation.
However, the types needed by the backend are few and static.
It makes more sense to use a struct for them
and to hang that struct off the ssa.Config,
which is the correct home for readonly data.
Now that Types is a struct, we can clean up the names a bit as well.

This has the added benefit of allowing early construction
of all types needed by the backend.
This will be useful for concurrent backend compilation.

Passes toolstash-check -all. No compiler performance change.
