RISC-V: Implement ZKND and ZKNE extensions
This patch supports Zkne and Zknd extension.
It includes instruction's machine description and built-in funtions.
gcc/ChangeLog:
* config/riscv/constraints.md (D03): Add constants of bs and rnum.
(DsA): New.
* config/riscv/crypto.md (riscv_aes32dsi): Add ZKND's and ZKNE's instructions.
(riscv_aes32dsmi): New.
(riscv_aes64ds): New.
(riscv_aes64dsm): New.
(riscv_aes64im): New.
(riscv_aes64ks1i): New.
(riscv_aes64ks2): New.
(riscv_aes32esi): New.
(riscv_aes32esmi): New.
(riscv_aes64es): New.
(riscv_aes64esm): New.
* config/riscv/riscv-builtins.cc (AVAIL): Add ZKND's and ZKNE's AVAIL.
* config/riscv/riscv-scalar-crypto.def (DIRECT_BUILTIN): Add ZKND's and
ZKNE's built-in functions.
gcc/testsuite/ChangeLog:
* gcc.target/riscv/zknd32.c: New test.
* gcc.target/riscv/zknd64.c: New test.
* gcc.target/riscv/zkne32.c: New test.
* gcc.target/riscv/zkne64.c: New test.
