  Drop tag arguments early on backends than don't use them

Reviewed by Yusuke Suzuki.

The extra arguments to call/jmp for pointer tagging are only used on
arm64e. However, on all risc platforms, riscLowerMalformedImmediates
will emit extra code to load the values in a register.

Instead, drop the extra tag arguments early so that none of the other
passes can get confused.
