[PATCH] Remove -fstrict-overflow, default to undefined signed integer and pointer overflow

The following removes the third state we had apart from signed integer overflow wrapping and being undefined. It makes signed integer overflow undefined, consistently at all optimization levels. -fno-strict-overflow stays as a backward compatible way to avoid optimizations that rely on signed in
