Robert Griesemer	4360fd8d6f	go/types, types2: use "and not used" instead of "but not used" in error messages ... This matches longstanding compiler behavior. Also, for unused packages, report: `"pkg" imported and not used` `"pkg" imported as X and not used` This matches the other `X declared and not used` errors. For #55326.

Shenghou Ma	449b6abbac	cmd/compile/internal/gc: reword "declared and not used" error message ... "declared and not used" is technically correct, but might confuse the user. Switching "and" to "but" will hopefully create the contrast for the users: they did one thing (declaration), but not the other --- actually using the variable. This new message is still not ideal (specifically, declared is not entirely precise here), but at least it matches the other parsers and is one step in the right direction.

Keith Randall	1fb596143c	cmd/compile: don't bother compiling functions named "_" ... They can't be used, so we don't need code generated for them. We just need to report errors in their bodies. This is the minimal CL for 1.12. For 1.13, CL 158845 will remove a bunch of special cases sprinkled about the compiler to handle "_" functions, which should (after this CL) be unnecessary.
