This CL renames blank functions in the test/ directory so that they don't rely on the compiler doing anything more than typechecking them. In particular, I ran this search to find files that used blank functions and methods: $ git grep -l '^func.*\b_(' | xargs grep -n '^' | grep '\.go:1:' | grep -v '// errorcheck$' I then skipped updating a few files: * blank.go * fixedbugs/issue11699.go * fixedbugs/issue29870.go These tests specifically check that blank functions/methods work. * interface/fail.go Not sure the motivation for the blank method here, but it's empty anyway. * typeparam/tparam1.go Type-checking test, but uses "-G" (to use types2 instead of typecheck). Updates #47446.
