[Bug c/61240] [4.8/4.9/4.10 Regression] Incorrect warning "integer overflow in expression" on pointer-pointer subtraction

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=61240 --- Comment #7 from Marek Polacek --- But C++ has its own pointer_diff version that doesn't do such optimization. With my change the C FE would generate the same expr as the C++ FE. And FEs shouldn't perform such optimizations anyway.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=61240 --- Comment #6 from Jakub Jelinek --- But in that case we should have an adequate replacement on the match_and_simplify side.
