[integration 1/4] RISC-V/rvv: Added assembly pseudoinstructions, vfabs.v.

[Nelson Chu]

vfabs.v vd,vs = vfsgnjx.vv vd,vs,vs

gas/
    * testsuite/gas/riscv/extended/vector-insns-fail-arith-floatp.l: Updated.
    * testsuite/gas/riscv/extended/vector-insns-fail-arith-floatp.s: Likewise.
    * testsuite/gas/riscv/extended/vector-insns.d: Likewise.
    * testsuite/gas/riscv/extended/vector-insns.s: Likewise.
opcodes/
    * riscv-opc.c: Added vfabs.v as an alias of vfsgnjx.vv.
