    RISC-V: testsuite: Fix vmul test expectation and fix -ffast-math.
    
    I forgot to check for vfmul in the multiplication tests as well as
    some -ffast-math arguments.  Fix this.
    
    gcc/testsuite/ChangeLog:
    
            * gcc.target/riscv/rvv/autovec/binop/vadd-run.c: Add
            -ffast-math.
            * gcc.target/riscv/rvv/autovec/binop/vadd-zvfh-run.c: Dito.
            * gcc.target/riscv/rvv/autovec/binop/vrem-rv32gcv.c: Remove
            -ffast-math
            * gcc.target/riscv/rvv/autovec/binop/vmul-rv32gcv.c: Check for
            vfmul.
            * gcc.target/riscv/rvv/autovec/binop/vmul-rv64gcv.c: Dito.
