* config/pa/tm-hppa.h (unwind_table_entry): Use one of the
reserved fields to hold a stub unwind entry type. Fix typo.
(stub_unwind_entry): New structure for raw stub unwind entries.
(stub_unwind_types): The types of stubs we may encounter.
(UNWIND_ENTRY_SIZE, STUB_UNWIND_ENTRY_SIZE): New defines.
* hppa-tdep.c (rp_saved): Use additional information provided
by linker stub unwind descriptors.
(frameless_function_invocation): Likewise.
(frame_chain_valid): Likewise.
* paread.c (compare_unwind_entries): New function for sorting
unwind table entries.
(read_unwind_info): Rewrite to remove dependency on host endianness.
Read in data from the $UNWIND_END$ subspace which contains linker
stub unwind descriptors. Merge that data into the basic unwind
table.
