Summary Non-arm64e/x86 platforms load otherwise ignored tag arguments to call/jmp

The extra arguments to call/jmp for pointer tagging are only used on arm64e (and are ignored during code generation on other platforms). However, on risc platforms, generic passes that convert large immediates to "load immediate into reg + use reg" sequences will pointlessly generate instructions to load any extra arguments into regs. This is dead code.
