Cuong Manh Le a72622d028 cmd/compile: skip "_" function in reflectdata.MarkUsedIfaceMethod
CL 256798 added compiler ability to retain only used interface methods,
by generating a mark relocation whenever an interface method is used. To
do that, the compiler needs the current function linker object.

However, for unnamed function "func _()", its linker object is nil,
causes the compiler crashes for code in #45258.

CL 283313 fixed the code in #45258 unintentionally, since when the
compiler now does not walk unnamed functions anymore.

This CL fixes the root issue, by making reflectdata.MarkUsedIfaceMethod
skips unnamed functions, and also adding regression test.

Fixes #45258
