aarch64: Implement system register r/w arm ACLE intrinsic functions
Implement the aarch64 intrinsics for reading and writing system
registers with the following signatures:
uint32_t __arm_rsr(const char *special_register);
uint64_t __arm_rsr64(const char *special_register);
void* __arm_rsrp(const char *special_register);
float __arm_rsrf(const char *special_register);
double __arm_rsrf64(const char *special_register);
void __arm_wsr(const char *special_register, uint32_t value);
void __arm_wsr64(const char *special_register, uint64_t value);
void __arm_wsrp(const char *special_register, const void *value);
void __arm_wsrf(const char *special_register, float value);
void __arm_wsrf64(const char *special_register, double value);
