Robert Griesemer d93f02010c cmd/compile/internal/types2: only mark variables as used if they are
Marking variables in erroneous variable declarations as used is
convenient for tests but doesn't necessarily hide follow-on errors
in real code: either the variable is not supposed to be declared in
the first place and then we should get an error if it is not used,
or it is there because it is intended to be used, and the we expect
an error it if is not used.

This brings types2 closer to go/types.
