    [PATCH v4] [target/116592] RISC-V: Fix illegal operands "th.vsetvli
zero,0,e32,m8" for XTheadVector

    Since the THeadVector vsetvli does not support vl as an immediate, we
    need to convert 0 to zero when outputting asm.

    gcc/ChangeLog:

            * config/riscv/thead.cc (th_asm_output_opcode): Change '0' to
            "zero"

    gcc/testsuite/ChangeLog:

            * gcc.target/riscv/rvv/xtheadvector/pr116592.c: New test.
