76842ac3fd [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

ecb30c670f [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.

40a6669538 [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).

e4c7b73897 [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.

a189c8b6e2 [yul-phaser] Pass unique_ptr rather than a mutable reference to Program::applyOptimisationSteps()
- Giving the function ownership of an object and then receiving back another object is better than letting it implicitly modify data passed in an argument.

785f65d0f5 [yul-phaser] Make Program and Population classes accept source code rather than file path
- I need some sample .yul files for testing but I see that existing tests generally have source code hard-coded in them rather than in standalone .yul files. There are lots of .yul files but they seem to be automatically processed by a special test case rather loaded ad-hoc by manually created tests.
- Program and Population required a file name until now. I'm making them accept loaded source code to be able to give them data hard-coded in a test.

14d726ff01 [yul-phaser] Program: Use unique_ptr rather than shared_ptr to hold a pointer to the AST root
