Add SVE register defines
In order to prevent gaps in the register numbering, the Z registers
reuse the V register numbers (which become pseudos on SVE).
2018-06-01 Alan Hayward <alan.hayward@arm.com>
* aarch64-tdep.c (aarch64_sve_register_names): New const
var.
* arch/aarch64.h (enum aarch64_regnum): Add SVE entries.
(AARCH64_SVE_Z_REGS_NUM): New define.
(AARCH64_SVE_P_REGS_NUM): Likewise.
(AARCH64_SVE_NUM_REGS): Likewise.
