aarch64: Add new +rcpc2 flag
gcc/ChangeLog:
* config/aarch64/aarch64-arches.def (V8_4A): Add RCPC2.
* config/aarch64/aarch64-option-extensions.def
(RCPC2): New flag.
(RCPC3): Add RCPC2 dependency.
* config/aarch64/aarch64.h (TARGET_RCPC2): Use new flag.
gcc/testsuite/ChangeLog:
* gcc.target/aarch64/cpunative/native_cpu_21.c: Add rcpc2 to
expected feature string instead of rcpc.
* gcc.target/aarch64/cpunative/native_cpu_22.c: Ditto.
