* tree-ssa-propagate.c (set_rhs): Restructure validity tests as a
test for inclusion rather than as a test for exclusion.
* tree-ssa-ccp.c (fold_stmt_r) <COND_EXPR>: Use set_rhs to modify
the condition after calling fold_binary.
* fold-const.c (fold_inf_compare): Remove in_gimple_form check.
(fold_binary) <LT_EXPR, GT_EXPR, LE_EXPR, GE_EXPR>: Likewise.
* builtins.c (fold_builtin_isascii): Likewise.
(fold_builtin_isdigit): Likewise.
