This commit renames two AArch64 predicates in GCC’s machine description files to better reflect their usage. The aarch64_imm3 predicate, which previously had a limited range and was used for shift amounts in extended register operations, is renamed to aarch64_shift_imm3. Concurrently, aarch64_lane_imm3 is renamed to aarch64_imm3 to represent a more general immediate value suitable for lane selection. These changes improve the readability and maintainability of the AArch64 target configuration.
