For grouped type declarations, go/doc introduces
fake individual declarations. Don't use the original
location of the "type" keyword because it will lead
to an overly large source code range for that fake
declaration, and thus an overly large selection shown
via godoc (e.g.: click on the AssignStmt link for:
http://golang.org/pkg/go/ast/#AssignStmt ).

Also: Don't create a fake declaration if not needed.

Also allow multiple invalid import statements in a
single file.

Fixes #3021. The changes to go/parser and the
language specifcation have already been committed.

We were not aligning the code size,
so read-only data, which follows in the same
segment, could be arbitrarily misaligned.

Avoids global array buffer overflows if they are
indexed using some of the values between NTYPE
and NALLTYPE.  It is entirely likely that not all of these
are necessary, but this is the C compiler and not worth
worrying much about.  This change takes up only a
few more bytes of memory and makes the behavior
deterministic.
