which is either commented out or ifdef'd out.  Add, update and
clean comments.  Fix various indention and spacing problems.  Handle
problems related to using "ble" to jump to a stub rather than "bl"
(%r31 is trashed by "ble", but not by "bl").
(NEW_INSTRUCTION): Put inside curly braces.
(CURRENT_STUB_OFFSET): Fix indention problems.
(hppa_elf_build_arg_reloc_stub): Fix indention and spacing problems.
Add, update and clean comments.  Handle "ble" %r31 lossage problems.
(hppa_elf_build_long_branch_stub): Likewise.
(hppa_look_for_stubs_in_section): Likewise.
(hppa_elf_stub_check): Remove obsolete function.

* hppa_stubs.h: Add new instructions to deal with %r31 lossage
problems.  Delete unused instructions.
