(mips_gp_save_slot): Declare.
* config/mips/mips.c (mips_restore_gp): Remove in favor of...
(mips_gp_save_slot): ...this new function.
* config/mips/mips.md (exception_receiver): Use mips_gp_save_slot
and mips_output_move to generate the output template.
(call_internal): Force splitting if TARGET_SPLIT_CALLS. Don't emit
a gp load after a noreturn call. Load the gp using a move rather
than an exception_receiver pattern.
(call_value_internal, call_value_multiple_internal): Likewise.
(call_split, call_value_split, call_value_multiple_split): Clobber $28.
