go/types: review of expr.go

The changes from the (reviewed) dev.regabi copy of expr.go can be seen
by comparing patchset 2 and 7. The actual change is some small
improvements to readability and consistency in untyped conversion,
adding some missing documentation, and removing the "// REVIEW
INCOMPLETE" marker.

Note that expr.go diverges from types2 in its handling of untyped
conversion.
