Dan Scales 29483b3dae test: re-enable a bunch of tests with types2
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.
