treewide: rework numeric value handling
- Parse integer literals as unsigned numeric values in order to be able
to represent the entire unsigned 64bit value range
- Stop parsing minus-prefixed integer literals as negative numbers but
treat them as separate minus operator followed by a positive integer
instead
- Only store unsigned numeric constants in bytecode
- Rework numeric comparison logic to be able to handle full 64bit
unsigned integers
- If possible, yield unsigned 64 bit results for additions
- Simplify numeric value conversion API
- Compile code with -fwrapv for defined signed overflow semantics
