[dev.regabi] cmd/compile/internal/gc: add MethodName for getting referenced method A common operation throughout the front end is getting the ONAME for a method used in a method selector, method expression, or method value. This CL adds MethodName as a uniform API for doing this for all of these kinds of nodes. For method selectors (ODOTMETH) and method expressions (ONAMEs where isMethodExpression reports true), we take advantage of the Node.Opt field to save the types.Field. This is the approach we already started taking in golang.org/cl/271217 (caching types.Field in Node.Opt for ODOT). For method values (OCALLPART), we continue using the existing callpartMethod helper function. Escape analysis already uses Node.Opt for tracking the method value's closure's data flow. A subsequent, automated refactoring CL will make more use of this method. For now, we just address a few cases in inl.go that aren't easily automated. Passes toolstash-check.
