re PR middle-end/92063 (ICE in operation_could_trap_p, at tree-eh.c:2528 when compiling Python's Python/_warnings.c)
PR middle-end/92063
* tree-eh.c (operation_could_trap_helper_p) <case COND_EXPR>
<case VEC_COND_EXPR>: Return false with *handled = false.
(tree_could_trap_p): For {,VEC_}COND_EXPR return false instead of
recursing on the first operand.
* fold-const.c (simple_operand_p_2): Use generic_expr_could_trap_p
instead of tree_could_trap_p.
* tree-ssa-sccvn.c (vn_nary_may_trap): Formatting fixes.
* gcc.c-torture/compile/pr92063.c: New test.
