compiler: always sort interface parse methods The exporter relies on sorting interface parse methods. It would sort them as it encountered interface types. However, when an interface type is an element of a struct or array type, the exporter might encounter that interface type before sorting the parse methods. If it then encountered an identical interface type again, it could get confused about whether the two types are identical or not. Fix the problem by always sorting the parse methods in the finalize_methods pass. Also firm up the export type sorting to make sure we never have this kind of confusion again. Doing this revealed that we need to be more careful about sorting in order to handle aliases correctly. Also fix the interface type hash computation to use the right hash value when looking at parse methods rather than all methods. The test case for this is https://go.dev/cl/405759.

This is a compiler frontend for the Go programming language. The frontend was originally developed at Google, and was released in November 2009. It was originally written by Ian Lance Taylor.
It was originally written for GCC. As of this writing it only supports GCC, but the GCC support has been separated from the rest of the frontend, so supporting another compiler is feasible.
The go subdirectory holds the frontend source code. This is mirrored to the gcc/go subdirectory in the GCC repository.
The libgo subdirectory holds the library source code. This is a copy of the main Go library with various changes appropriate for this compiler. The main Go library is hosted at http://go.googlesource.com/go, in the src directory. The libgo subdirectory is mirrored to the libgo subdirectory in the gcc repository.
