gas HANDLE_ALIGN and frag_alloc
This adds the section to HANDLE_ALIGN args, so that the frag created
by the ppc backend can be properly allocated on the frag obstack.
I've added an extra param to frag_alloc too, for cases where we know
the frag requires at least some bytes in fr_literal. This simplifies
some existing code, for example in compress_debug and relax_segment.
In the case of the relax_segment code, I think we may have had a bug
there in using obstack_blank_fast, which doesn't check that the frag
has room.
