AArch64: Add pauth DWARF registers
Map the pauth registers to DWARF.
Add a new pseudo register ra_state and also map this to DWARF. This register
is hidden from the user - prevent it from being read or written to. It will
be used for the unmangling of addresses.
gdb/ChangeLog:
* aarch64-tdep.c (aarch64_dwarf_reg_to_regnum): Check for pauth
registers.
(aarch64_pseudo_register_name): Likewise.
(aarch64_pseudo_register_type): Likewise.
(aarch64_pseudo_register_reggroup_p): Likewise.
(aarch64_gdbarch_init): Add pauth registers.
* aarch64-tdep.h (AARCH64_DWARF_PAUTH_RA_STATE): New define.
(AARCH64_DWARF_PAUTH_DMASK): Likewise.
(AARCH64_DWARF_PAUTH_CMASK): Likewise.
(struct gdbarch_tdep): Add regnum for ra_state.
