re PR middle-end/3074 (Statement with no effect not flagged with -Wall)
PR middle-end/3074
* fold-const.c (strip_compound_expr): Delete function.
(count_cond): Delete function.
(fold_binary_op_with_conditional_arg): Only perform transformations
"a + (b?c:d) -> b ? a+c : a+d" and "(b?c:d) + a -> b ? c+a : d+a"
when a is constant. This greatly simplifies this routine.
* tree.c (saved_expr_p): Delete function.
* tree.h (saved_expr_p): Delete function prototype.
* gcc.dg/pr3074-1.c: New test case.
* gcc.dg/sequence-pt-1.c: Remove an XFAIL.
