[Constraint solver] Handle disjunctions as separate connected components.
...
The constraint graph models type variables (as the nodes) and
constraints (as the multi-edges connecting nodes). The connected
components within this (multi-)graph are independent subproblems that
are solved separately; the results from each subproblem are then
combined. The approach helps curtail exponential behavior, because
(e.g.) the disjunctions/type variables in one component won't ever be
explored while solving for another component
This approach assumes that all of the constraints that cannot be
immediately solved are associated with one or more type
variables. This is almost entirely true---constraints that don't
involve type variables are immediately simplified.
Except for disjunctions. A disjunction involving no type variables
would not appear *at all* in the constraint graph. Worse, it's
independence from other constraints could not be established, so the
constraint solver would go exponential for every one of these
constraints. This has always been an issue, but it got worse with the
separation of type checking of "as" into the "coercion" case and the
"bridging" case, which introduced more of these disjunctions. This led
to counterintuitive behavior where adding "as Foo" would cause the
type checking to take *more* time than leaving it off, if both sides
of the "as" were known to be concrete. rdar://problem/30545483
captures a case (now in the new test case) where we saw such
exponential blow-ups.
Teach the constraint graph to keep track of "orphaned" constraints
that don't reference any type variables, and treat each "orphaned"
constraint as a separate connected component. That way, they're solved
independently.
Fixes rdar://problem/30545483 and will likely curtain other
exponential behavior we're seeing in the solver.

AST: Fix GenericSignatureBuilder bug with protocol typealiases
...
If a nested type of a generic parameter was a typealias, and the
generic parameter was not at depth 0, index 0, we would resolve
the type down to the wrong PotentialArchetype, causing bogus
diagnostics and crashes.
Make sure we apply a substitution to the typealias's underlying
type before resolving it, to map it to the correct PotentialArchetype.
Note that the original test case in the radar works now, but the more
comprehensive test I added exposes an existing problem where generic
signature canonicalization is not idempotent. When this is fixed,
the RUN: line in the test can be changed from -typecheck to -emit-ir.
Fixes <rdar://problem/30248571>.

Cache expression types in failure diagnosis.
...
After we call into typeCheckExpression() we need to cache the
resulting types in the constraint system type map because we later
call into code that reads the types out of the type map.
Fixes rdar://problem/30376186 as well as a couple crashers.

[Serialization] Improve extensions of nested types with the same name ( #7397 )
...
Previously looking up an extension would result in all extensions for
types with the same name (nested or not) being deserialized; this
could even bring in base types that had not been deserialized yet. Add
in a string to distinguish an extension's base type; in the top-level
case this is just a module name, but for nested types it's a full
mangled name.
This is a little heavier than I'd like it to be, since it means we
mangle names and then throw them away, and since it means there's a
whole bunch of extra string data in the module just for uniquely
identifying a declaration. But it's correct, and does less work than
before, and fixes a circularity issue with a nested type A.B.A that
apparently used to work.

Replace concrete init(stringInterpolationSegment:)'s with generic ones
...
Remove 16 concrete init(stringInterpolationSegment:) overloads and
replace them with 3 generic overloads, significantly reducing the
exponential blow-up from larger string interpolations.
