alloc gas seginfo on notes obstack
Lots of memory used in gas should go on this obstack. The patch also
frees all the gas obstacks on exit, which isn't a completely trivial
task.
* subsegs.c (alloc_seginfo): New function.
(subseg_change, subseg_get): Use it.
(subsegs_end): New function.
* as.h (subsegs_end): Declare.
* output-file.c: Include subsegs.h
(stash_frchain_obs): New function.
(output_file_close): Save obstacks attached to output bfd before
closing. Call subsegs_end with the array of obstacks.
