VEC_COND_EXPR code cleanup
This removes now unnecessary special-casings of VEC_COND_EXPRs after
making its first operand a gimple value.
2021-04-14 Richard Biener <rguenther@suse.de>
* genmatch.c (lower_cond): Remove VEC_COND_EXPR special-casing.
(capture_info::capture_info): Likewise.
(capture_info::walk_match): Likewise.
(expr::gen_transform): Likewise.
(dt_simplify::gen_1): Likewise.
* gimple-match-head.c (maybe_resimplify_conditional_op):
Remove VEC_COND_EXPR special-casing.
(gimple_simplify): Likewise.
* gimple.c (gimple_could_trap_p_1): Adjust.
* tree-ssa-pre.c (compute_avail): Allow VEC_COND_EXPR
to participate in PRE.
