David Chase a2d92b5143 cmd/compile: register abi, morestack work and mole whacking
Morestack works for non-pointer register parameters

David Chase 998fe70b68 cmd/compile: fixed which-result confusion in presence of 0-width types
A function returning multiple results, some of them zero-width,
will have more than one result present at an offset.  Be sure
that offset AND type match.

Includes test.
