The strict_overflow_p flag was removed from the tree_single_nonzero_warnv_p helper function. This helper is part of the larger tree_expr_nonzero_warnv_p function, which aims to eliminate a call to fold_overflow_warning(). As part of the change, the helper was renamed to tree_single_nonzero_p to reflect that it no longer handles overflow warnings directly. This change also impacts c-ubsan.cc, gimple-range-fold.cc, ipa-prop.cc, tree-ssa-phiopt.cc, and value-query.cc.
