RISC-V: Allow vector constants in riscv_const_insns.
This patch adds various vector constants to riscv_const_insns in order
for them to be properly recognized as immediate operands. This then
allows to emit vmv.v.i instructions via autovectorization.
gcc/ChangeLog:
* config/riscv/riscv.cc (riscv_const_insns): Add permissible
vector constants.
gcc/testsuite/ChangeLog:
* gcc.target/riscv/rvv/autovec/vmv-imm-rv32.c: New test.
* gcc.target/riscv/rvv/autovec/vmv-imm-rv64.c: New test.
* gcc.target/riscv/rvv/autovec/vmv-imm-template.h: New test.
* gcc.target/riscv/rvv/autovec/vmv-imm-run.c: New test.
