There should be a way to perform basic arithmetic operations which can potentially overflow, such as addition, subtraction, and multiplication, and get the result as well as a boolean indicating whether it overflowed.

See for inspiration:
http://clang.llvm.org/docs/LanguageExtensions.html#checked-arithmetic-builtins

In debug mode, we might codegen this every time and do a panic if overflow occurs.
