I made the default be that, where there are differences between types2 and -G=0 error messages, we want errorcheck tests to pass types2. Typically, we can get errorcheck to pass on types2 and -G=0 if they give the same number of error messages on the same lines, just different wording. If they give a different number of error messages, then I made types2 pass. I added an exception list for -G=0 to cover those cases where -G=0 and types give different numbers of error messages. Because types2 does not run if there are syntax errors, for several tests, I had to split the tests into two parts in order to get all the indicated errors to be reported in types2 (bug228.go, bug388.go, issue11610.go, issue14520.go) I tried to preserve the GCCGO labeling correctly (but may have gotten some wrong). When types2 now matches where a GCCGO error previously occurred, I transformed GCCGO_ERROR -> ERROR. When types2 no longer reports an error in a certain place, I transformed ERROR -> GCCGO_ERROR. When types2 reports an error in a new place, I used GC_ERROR. The remaining entries in types2Failures are things that I think we probably still need to fix - either actually missing errors in types2, or cases where types2 gives worse errors than -G=0.
