    RISC-V: Bugfix for RVV floating-point rm suffix sequence
    
    According to below RVV intrinsic doc, the RVV floating-point intrinsic name
    with rounding mode should be:
    
    _rm_m
    
    instead of:
    
    _m_rm
    
    https://github.com/riscv-non-isa/rvv-intrinsic-doc/pull/226
    
    This patch fix this naming sequence issue and adjust the test cases.
    
    Signed-off-by: Pan Li <pan2.li@intel.com>
    
    gcc/ChangeLog:
    
            * config/riscv/riscv-vector-builtins-shapes.cc (struct alu_frm_def):
            Move rm suffix before mask.
    
    gcc/testsuite/ChangeLog:
    
            * gcc.target/riscv/rvv/base/float-point-frm-insert-1.c: Adjust
            test cases.
            * gcc.target/riscv/rvv/base/float-point-frm.c: Ditto.
