FYI, a newer patch has been posted:

I don't think it is necessary to test the op of vpermil again if it is
CONST_INT, we know it is not 0..3 because otherwise
insn_data[icode].operand[i + 1].predicate (op, mode)
would be true.
_mm_com* don't seem to have an constant argument, just two vector arguments, so
there is nothing to check.  The immediate comes directly from the table and so
is known to be ok.
