[release-branch.go1.20] cmd/compile: relax overly strict assertion

The assertion here was to make sure the newly constructed and
typechecked expression selected the same receiver-qualified method,
but in the case of anonymous receiver types we can actually end up
with separate types.Field instances corresponding to each types.Type
instance. In that case, the assertion spuriously failed.

The fix here is to relax and assertion and just compare the method's
name and type (including receiver type).

Fixes #58776.
