aarch64: Implement 128-bit extension to ACLE sysreg r/w builtins
Implement the ACLE builtins for 128-bit system register manipulation:
* __uint128_t __arm_rsr128(const char *special_register);
* void __arm_wsr128(const char *special_register, __uint128_t value);
gcc/ChangeLog:
* config/aarch64/aarch64-builtins.cc (AARCH64_RSR128): New
`enum aarch64_builtins' value.
(AARCH64_WSR128): Likewise.
(aarch64_init_rwsr_builtins): Init `__builtin_aarch64_rsr128'
and `__builtin_aarch64_wsr128' builtins.
(aarch64_expand_rwsr_builtin): Extend function to handle
`__builtin_aarch64_{rsr|wsr}128'.
* config/aarch64/aarch64-protos.h (aarch64_retrieve_sysreg):
Update function signature.
* config/aarch64/aarch64.cc (F_REG_128): New.
(aarch64_retrieve_sysreg): Add 128-bit register mode check.
* config/aarch64/aarch64.md (UNSPEC_SYSREG_RTI): New.
(UNSPEC_SYSREG_WTI): Likewise.
(aarch64_read_sysregti): Likewise.
(aarch64_write_sysregti): Likewise.
* config/aarch64/arm_acle.h (__arm_rsr128): New.
(__arm_wsr128): Likewise.
