Currently bindings where inferred on every bindTypeVariable call,
but that's wasteful because not all binds are always correct. To
avoid unnecessary inference traffic let's wait until re-activated
constraints are simplified and notify binding inference about new
fixed type only if all of them are successful.

This is a follow-up to #35903.

[ConstraintSystem] NFC: Modernize SK_NonDefaultLiteral inference
654ec0d
@xedin
[ConstraintGraph] Extract logic related to fixed types into dedicated…
166c41d 
… methods on graph node
@xedin
[CSBindings] Use matchTypes directly while attempting a type variable
f12efe9 
This makes sure that solver knows the result of a bind, instead of
having to checking `failedConstraint` and allows passing flags.
@xedin
[ConstraintSystem] Delay inference until let's clear that type variab…
b487b69 
…le attempt is successful

Currently bindings where inferred on every `bindTypeVariable` call,
but that's wasteful because not all binds are always correct. To
avoid unnecessary inference traffic let's wait until re-activated
constraints are simplified and notify binding inference about new
fixed type only if all of them are successful.
@xedin
[ConstraintGraph] Don't propagate to referenced vars
ca16c37 
Just like regular `Bind` constraint `BindOverload` contains no
useful information for referenced type variables.
@xedin xedin force-pushed the followup-to-incremental-bindings branch from d78b994 to ca16c37 Compare March 1, 2021 18:52
