The compiler has logic to check whether we implicitly dereferenced a
defined pointer while trying to select a method. However, rather than
checking whether there were any implicit dereferences of a defined
pointer, it was finding the innermost dereference/selector expression
and checking whether that was dereferencing a named pointer. Moreover,
it was only checking defined pointer declared in the package block.
This CL restructures the code to match go/types and gccgo's behavior.
Fixes #43384.
