Djordje Mijovic 9b3d1c11ff yul-phaser: A few more tweaks to ensure that signedness conversions do not cause warnings
- Don't cast booleans to int when the result gets assigned to an unsigned type. Relace them with ifs.
- Use unsigned initializer for a variable declared in a lambda capture.
- Unsigned abs() of a difference of unsigned values.
