  -----------
  Fix aarch64 MachRegister -> ROSE register conversion (#1843)

* Fix PC conversion

This handles both the 32-bit and 64-bit SP representations.

* Update conversion of zero register

This makes it more uniform and removes the hacky bit-twiddling of the
MachRegister by name.

* Update conversion of stack pointer

This makes it more uniform and removes the hacky bit-twiddling of the
MachRegister by name.

* Update conversion of pstate register

This makes it more uniform and removes the hacky bit-twiddling of the
MachRegister by name.

* Update conversion of GPRs

The register IDs are not guaranteed to be sequential, so it's not
possible to do arithmetic on them.

* Update conversion of FPRs

The register IDs are not guaranteed to be sequential, so it's not
possible to do arithmetic on them.

* Update conversion of pstate flags

This makes it uniform with the other conversions. Note: the complete
pstate register is treated separately from its individual fields in
ROSE.
