5b320992ea [Constraint solver] Use a constraint system to apply all function builders. 
When type checking the body of a function declaration that has a function
builder on it (e.g., `@ViewBuilder var body: some View { ... }`), create a
constraint system that is responsible for constraint generation and
application, sending function declarations through the same code paths
used by closures.

function as well as a closure.

c6b6e72aac [CS] Tighten up assertions for getCalleeDeclAndArgs 
Assert that we have a correct locator and that we
recorded argument information for it, rather than
returning no information.

In addition, always return the callee locator,
even if there is no callee.

afc6ccdeb5 Re-land parsing and printing for Clang function types. 
This reverts commit e805fe486e, which reverted
the change earlier. The problem was caused due to a simultaneous change to some
code by the PR with parsing and printing for Clang function types (#28737)
and the PR which introduced Located<T> (#28643).

This commit also includes a small change to make sure the intersecting region
is fixed: the change is limited to using the fields of Located<T> in the
`tryParseClangType` lambda.

dfda7aca7f [Constraint solver] Generalize "target" of solution application. 
Chip away at the expression-centric nature of the constraint system by
generalizing the "target" of solution application from a single
expression to a a "SolutionApplicationTarget", which can be an
expression or a function body. The latter will be used for applying
function builders to an entire function body.
