[yul-phaser] Population: Evaluate fitness immediately when an individual is added or modified
...
- This removes the explicit evaluation phase.
- Fitness is no longer optional in Individual

[yul-phaser] Population: Make ordering of individuals with same fitness deterministic and prioritise shorter chromosomes
...
- Before this change the order of chromosomes with the same fitness in a population depended on the initial order set when the population was first created. Now it only depends on the individual.
- The length comparison is not strictly necessary (lexicographical order covers that) but it makes the intention clear and the comparison slightly faster when chromosomes have different lengths.

[yul-phaser] Population: Extract a function for comparing fitness of individuals
...
- Mostly for readability and convenience. This significantly shortens calls to sort().
- I could define it as Individual::operator< instead but it would be inconsistent with operator== because it does not compare the chromosomes, only fitness. It could result in an unintuitive situation where (a <= b <= a) does not necessarily imply (a == b).

[yul-phaser] Store already loaded program in Population and make copies when computing fitness
...
- Until now the source code was being parsed during every fitness computation. Now the parsed program is reused and only the optimisation steps are applied each time.
