10ef3d66 - [PowerPC] Align bcdsetsign Sema validation with other BCD builtins (#178121)

[PowerPC] Align bcdsetsign Sema validation with other BCD builtins (#178121) `__builtin_ppc_bcdsetsign` currently uses standalone argument checks due to the `"t"` option. This change brings it in line with the helper-based validation used by other BCD builtins and adds Sema coverage.
