Add per-unit obstack
This adds an auto_obstack to the DWARF frame comp_unit object, and
then changes the remaining code here to use the comp_unit obstack
rather than the objfile obstack.
At this point, all the storage for frame data is self-contained --
that is, it is independent of the objfile.

* dwarf2/frame.c (struct comp_unit) <obstack>: New member.
(decode_frame_entry_1): Use the comp_unit obstack.
