RISC-V: Introduce XTheadVector as a subset of V1.0.0
This patch is to introduce basic XTheadVector support (march string parsing and a test for __riscv_xtheadvector) according to https://github.com/T-head-Semi/thead-extension-spec/ gcc/ChangeLog: * common/config/riscv/riscv-common.cc (riscv_subset_list::parse): Add new vendor extension. * config/riscv/riscv-c.cc (riscv_cpu_cpp_builtins): Add test marco. * config/riscv/riscv.opt: Add new mask. gcc/testsuite/ChangeLog: * gcc.target/riscv/predef-__riscv_th_v_intrinsic.c: New test. * gcc.target/riscv/rvv/xtheadvector.c: New test.
