Frank Chang 5c89e9c096 target/riscv: rvv-1.0: add evl parameter to vext_ldst_us() 
Add supports of Vector unit-stride mask load/store instructions
(vlm.v, vsm.v), which has:
    evl (effective vector length) = ceil(env->vl / 8).

The new instructions operate the same as unmasked byte loads and stores.
Add evl parameter to reuse vext_ldst_us().

Frank Chang d6c4d3f2a6 target/riscv: rvv-1.0: trigger illegal instruction exception if frm is not valid 
If the frm field contains an invalid rounding mode (101-111),
attempting to execute any vector floating-point instruction, even
those that do not depend on the rounding mode, will raise an illegal
instruction exception.

Call gen_set_rm() with DYN rounding mode to check and trigger illegal
instruction exception if frm field contains invalid value at run-time
for vector floating-point instructions.
