The `type_overflow` lint, doesn't catch the overflow for `i64` because the overflow happens earlier in the parse phase when the `u64` as biggest possible int gets casted to `i64` , without checking the for overflows. We can't lint in the parse phase, so a refactoring of the `LitInt` type was necessary. The types `LitInt`, `LitUint` and `LitIntUnsuffixed` where merged to one type `LitInt` which stores it's value as `u64`. An additional parameter was added which indicate the signedness of the type and the sign of the value.
