This PR contains the first handful of commits from @gregomni in #26140, with some adjustments. Specifically:

  • If an operator overload choice has the same type as an existing overload binding elsewhere in the expression, attempt that choice first. This is done by ordering such choices first in the main disjunction partition rather than using the favoring mechanism, because the solver will stop if it successfully finds a solution with a favored constraint, which could be incorrect.
  • Consider the number of favored choices when choosing which disjunction to try first in selectDisjunction.

These heuristics together help the solver reach a solution fast for expressions with multiple operators chained together where the operands all have the same type.

Finding a solution fast allows the solver to do more aggressive pruning later on. Once this change lands, I'm going to work on pruning heuristics for generic overloads, which I think will finally let us remove LinkedExprAnalyzer and the hacks around favored constraints. Once those hacks are removed, the favoring mechanism can be used to suggest choices that are likely to work without worrying about correctness.

All thanks to Greg for the approach taken in this PR!!

[ConstraintSystem] Allow the solver to find other solutions after
b9e08b2 
successfully finding a solution by favoring operators already bound
elsewhere.

Favoring existing operator bindings often lets the solver find a solution
fast, but it's not necessarily the best solution.

[Test] Adjust type checker performance tests

@hborla
[ConstraintSystem] Instead of favoring existing operator bindings,
c9100c4 
order them first in the main disjunction partition.
@hborla
[ConstraintSystem] Remove an unnecessary SIMD special case in
a8fcdb8 
`DisjunctionStep::shortCircuitDisjunctionAt`.

This code is unnecessary because SIMD overloads are in their own
partition, so the short circuiting will happen automatically.
@hborla
[ConstraintSystem] Re-instate the operator type variable merging

hacks for now.

There's some more disjunction pruning work to be done before we can
remove this.

[ConstraintSystem] For generic operators, only consider exact decls that
abfc903 
are already bound elsewhere for existingOperatorBindingsForDisjunction,
rather than also considering overload choices with the same type.
