compiler: allow to find appropriate methods via selectors

c.funcs contains function names using base types, while methods can be defined
on pointers and the value returned from c.getFuncNameFromSelector will have an
asterisk. We can't have the same name used for (*T) and (T) methods, so just
stripping the asterisk allows to get the right one.
