Pass an ABI identifier to hard_regno_call_part_clobbered
This patch replaces the rtx_insn argument to
targetm.hard_regno_call_part_clobbered with an ABI identifier, since
call insns are now just one possible way of getting an ABI handle.
This in turn allows predefined_function_abi::initialize to do the
right thing for non-default ABIs.
The horrible ?: in need_for_call_save_p goes away in a later patch,
with the series as a whole removing most direct calls to the hook in
favour of function_abi operations.
