compiler: report correct errors for sink methods

If somebody writes

func (s []int) _() {}

we should report an error.  Before this patch we were silently
accepting this code, because we didn't report any errors about the
receiver if the method was a sink.

This patch is unfortunately slightly complex to handle the case of

func (x int) _() {}

which we can only detect after define_global_names.

This fixes blank1.go in the current gc testsuite.
