efd357e7c7 [Constraint system] Factor out application to a SolutionApplicationTarget. 
Pull out the core operation of rewriting a given SolutionApplicationTarget
into into a method on the ExprWalker that does the overall rewrite, so it
can be called multiple times within application.

a308a7e53c [Constraint system] Sink down debug logging. 
This way we’ll see constraints whenever they’re generated, and remove some
of the expression-centric nature of the top-level solve() and solveImpl().

ffba71b889 [Parse] Add an attribute for typeEraser. 
This will be used for compiler-driven type erasure for dynamic
replacement of functions with an opaque return type. For now, just
parse the attribute and ignore it.

f5b9517552 [Constraint system] Simplify and improve handling of node tyoes. 
Rather than having separate dense maps for the type mappings of each
node type (expression, type location, variable declaration, pattern) that
a TypedNode can be, have a single such map. Sometimes we end up
setting a particular node's type more than once, so cope with that
by restoring the prior type.

a1932f10e5 [Constraint solver] Sink remaining logic from typeCheckBinding. 
Move the remaining logic of typeCheckBinding, which consists of applying
the solution to the pattern, down into the normal solution application
path. typeCheckBinding() is now a thin shell over the normal
typeCheckExpression() convenience function.

a54fbab8fd [ConstraintSystem] Favor resolving closures over any disjunction binding type variables 
Fix a case where favoring didn't account for "bound" type variable
being wrapped into optional(s) (disjunctions like that are used for
optional conversions). Doing so makes sure that closure result type
is not bound before the body of the closure is "opened", that's
important because body could provide additional context required
to bind result type e.g. `{ $0 as? <Type> }`.
