Add support for unions to our Python builtins type system ( #6541 )
...
## Summary
Fixes some TODOs introduced in
https://github.com/astral-sh/ruff/pull/6538 . In short, given an
expression like `1 if x > 0 else "Hello, world!"`, we now return a union
type that says the expression can resolve to either an `int` or a `str`.
The system remains very limited, it only works for obvious primitive
types, and there's no attempt to do inference on any more complex
variables. (If any expression yields `Unknown` or `TypeError`, we
propagate that result throughout and abort on the client's end.)

Replace NoHashHasher usages with FxHashMap ( #6049 )
...
## Summary
I had always assumed that `NoHashHasher` would be faster when using
integer keys, but benchmarking shows otherwise:

```
My guess is that `NoHashHasher` underperforms because the keys are not
randomly distributed...
Anyway, it's a ~1% (significant) performance gain on some of the above,
plus we get to remove a dependency.
