Special register id.

Constant	Description
kIdOs	Register that depends on OS, could be used as TLS offset.
kIdFp	Frame pointer register id.
kIdLr	Link register id.
kIdSp	Stack register id.
kIdZr	Zero register id. Although zero register has the same id as stack register it has a special treatment, because we need to be able to distinguish between these two at API level. Some instructions were designed to be used with SP and some other with ZR - so we need a way to distinguish these two to make sure we emit the right thing. The number 63 is not random, when you perform `id & 31` you would always get 31 for both SP and ZR inputs, which is the identifier used by AArch64 ISA to encode either SP or ZR depending on the instruction.

Test whether this register is ZR register.

Test whether this register is SP register.

Cast this register to a 32-bit W register (returns a new operand).

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Cast this register to a 64-bit X register (returns a new operand).

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
