Rework space/subspace handling in PA code to fully support
SOM spaces/subspaces.
* tc-hppa.c (USE_ALIASES): New object-format dependent define
to control the use of space/subspace name aliases.
(update_subspace): Accept space chain entry for containing space
as a new parameter. All callers changed.
(pa_get_label): Use current_space rather than pa_segment_to_space.
(pa_define_label): Likewise.
(pa_undefine_label): Likewise.
(md_begin): Change into the (possibly modified) text_section.
(pa_parse_space_stmt): Create a new segment/space if create_flag
is true, and the space name is not one of the two predefined spaces.
(pa_subspace): Use current_space rather than a lookup via
pa_segment_to_space. Reset BFD section flags as required by
the .subspace directive. Likewise for the section alignment.
Pass the current space to update_subspace and create_new_subspace.
(pa_spaces_begin): Only use space/subspace aliases if USE_ALIASES
is true. When not using aliases, create a BFD section for each
subspace encountered. When not using aliases replace the default
text, data, and bss segments with new ones.
(create_new_subspace): When not using aliases each subspace has a
section/segment and subsegments are not needed, so set the subsegment
to zero.
