Re: [PATCH v1 0/3] RISC-V: Combine vec_duplicate + vand.vv to vand.vx on GR2VR cost

[Robin Dapp]

This patch would like to introduce the combine of vec_dup + vand.vv into
vand.vx on the cost value of GR2VR.  The late-combine will take place if
the cost of GR2VR is zero, or reject the combine if non-zero like 1, 15
in test.  There will be two cases for the combine:

OK, thanks.
