RISC-V: Bugfix for max_sew_overlap_and_next_ratio_valid_for_prev_sew_p[pr117483]
This patch fixs https://gcc.gnu.org/bugzilla/show_bug.cgi?id=117483
If prev and next satisfy the following rules, we should forbid the case
(next.get_sew() < prev.get_sew() && (!next.get_ta() || !next.get_ma()))
in the compatible function max_sew_overlap_and_next_ratio_valid_for_prev_sew_p.
Otherwise, the tail elements of next will be polluted.
DEF_SEW_LMUL_RULE (ge_sew, ratio_and_ge_sew, ratio_and_ge_sew,
max_sew_overlap_and_next_ratio_valid_for_prev_sew_p,
always_false, use_max_sew_and_lmul_with_next_ratio)
Passed the rv64gcv full regression test.
