Re: [PATCH] RISC-V: Use VLS modes if the NITERS is known and smaller than VLS mode elements.

Hi Juzhe,

this LGTM.  I was first concerned whether we would want to
stop e.g. at LMUL = 1 and only continue with a specific flag but
actually this should be done via the costs.  If an implementation
wants to penalize or incentivize some behavior it can always
adjust the costs which should be sufficient.
