Enable a bunch of types2-related error tests to run successfully, so they no longer have to be disabled in run.go. - directive.go: split it into directive.go and directive2.go, since the possible errors are now split across the parser and noder2, so they can't all be reported in one file. - linkname2.go: similarly, split it into linkname2.go and linkname3.go for the same reason. - issue16428.go, issue17645.go, issue47201.dir/bo.go: handle slightly different wording by types2 - issue5609.go: handle slight different error (array length must be integer vs. array bound too large). - float_lit3.go: handle slightly different wording (overflows float vs cannot convert to float) I purposely didn't try to fix tests yet where there are extra or missing errors on different lines, since that is not easy to make work for both -G=3 and -G=0. In a later change, will flip to make the types2 version match correctly, vs. the -G=0 version.
