aarch64: Rename and improve aarch64_split_imm24
Two of the three uses of aarch64_imm24 included the important follow-up
tests vs aarch64_move_imm and aarch64_plus_operand. Lack of the exclusion
within aarch64_if_then_else_costs produced incorrect costing.
Since aarch64_split_imm24 has already matched a non-negative CONST_INT,
drill down from aarch64_plus_operand to aarch64_uimm12_shift.
gcc:
* config/aarch64/predicates.md (aarch64_split_imm24): Rename from
aarch64_imm24; exclude aarch64_move_imm and aarch64_uimm12_shift.
* config/aarch64/aarch64.md (*aarch64_bcond_wide_imm<GPI>):
Update for aarch64_split_imm24.
(*compare_cstore<GPI>_insn): Likewise.
* config/aarch64/aarch64.cc (aarch64_if_then_else_costs): Likewise.
