88dec5199e [Dependency Scanning] Add support for placing explicitly-built SDK modules into a separate module cache
With '-sdk-module-cache-path', Swift textual interfaces found in the SDK will be built into a separate SDK-specific module cache.
Clang modules are not yet affected by this change, pending addition of the required API.

6c22036931 [CSSimplify] NFC: Perform assignments to a key path in a separate method
Previously key path type didn't have any requirements on their
root and value types but now that they do, we need a dedicated
place to perform an assignment and open/record all of the requirements.

6d8b55a9f6 Sema: Split up gatherConstraints() into gatherAllConstraints() and gatherNearbyConstraints()
The two GatherKinds no longer share any implementation, so there's
no point keeping the logic together. Doing this also allows removing
the acceptConstraintFn from gatherAllConstraints(), which further
simplifies depthFirstSearch().

6a4d1a41c4 Prohibit isolated conformances with Sendable(Metatype) constraints
Within the constraint system, introduce a new kind of conformance constraint,
a "nonisolated conforms-to" constraint, which can only be satisfied by
nonisolated conformances. Introduce this constraint instead of the normal
conforms-to constraint whenever the subject type is a type parameter that
has either a `Sendable` or `SendableMetatype` constraint, i.e., when the type
or its values can escape the current isolation domain.

c69590fbdd [CS] Clean up pack expansion environment handling a little
- Track environments for `PackExpansionExpr` directly
instead of using a locator.
- Split up the querying and creation of the environment
such that the mismatch logic can be done directly in
CSSimplify instead of duplicating it.
- Just store the environment directly instead of
the shape and UUID.

23ace7d770 [ConstraintSystem] Store declaration context in which application occurs in ApplicableFunction constraint
This is required because `ApplicableFunction` constraint can
inject member reference constraints that require a declaration
context.

For example, `_ = { Double(...) }` would now produce a disjunction
for `Double.init` where overload choice declaration contexts point
to the closure instead of the enclosing context.

This addresses a long-standing FIXME in `simplifyApplicableFnConstraint`
and helps with disjunction optimizer because its correctness depends on
correct identification of declaration contexts where applications happen.
