c2ccb874ab Soften actor isolation in closures passed to @preconcurrency
When a closure is not properly actor-isolated, but we know that we inferred its isolation from a `@preconcurrency` declaration, we now emit the errors as warnings in Swift 5 mode to avoid breaking source compatibility if the isolation was added retroactively.

b97ef02d85 Opaque opaque types and compute substitutions in the constraint system
Opaque opaque types and record them within the "opened types" of the
constraint system, then use that information to compute the set of
substitutions needed for the opaque type declaration using the normal
mechanism of the constraint solver. Record these substitutions within
the underlying-to-opaque conversion.

Use the recorded substitutions in the underlying-to-opaque conversion
to set the underlying substitutions for the opaque type declaration
itself, rather than reconstructing the substitutions in an ad hoc manner
that does not account for structural opaque result types.

1b3c0b7a73 [Regex] Infer capture types of regex literals.
When parsing a regular expression literal, accept a serialized capture structure from the regex parser. During type checking, decode it and form Swift types.

Examples:
```swift
'/(.)(.)/' // ==> `Regex<(Substring, Substring)>`
'/(?<label>.)(.)/' // ==> `Regex<(label: Substring, Substring)`
'/((.))*((.)?)/' //==> `Regex<([Substring], [Substring], Substring, Substring?)>`
```

Also:
- Fix a bug where a regex literal parsing error is not returning an error parser result.

Note:
- This needs to land after apple/swift-experimental-string-processing#92 and after `dev/4` tag has been created.
- See apple/swift-experimental-string-processing#92 for regex parser changes and the capture structure encoding.
- The `RegexLiteralParsingFn` `CaptureStructureOut` pointer type change from `char *` to `void *` will not break builds due to implicit pointer conversion (SE-0324) and unchanged ABI.

Resolves rdar://83253511.

128f5d4bc6 Update regex literal lexing and emission
Update the lexing implementation to defer to the
regex library, which will pass back the pointer
from to resume lexing, and update the emission to
call the new `Regex(_regexString:version:)`
overload, that will accept the regex string with
delimiters.

Because this uses the library's lexing
implementation, the delimiters are now `'/.../'`
and `'|...|'` instead of plain `'...'`.

3b66a31d5c Model Pack Expressions and Pack Reifications
Pack expressions take a series of argument values and bundle them together as a pack - much like how a tuple expression bundles argument expressions into a tuple.

Pack reification represents the operation that converts packs to tuples/scalar types in the AST. This is important since we want pack types in return positions to resolve to tuples contextually.

05363cd55a Regex literal runtime plumbing.
- Frontend: Implicitly import `_StringProcessing` when frontend flag `-enable-experimental-string-processing` is set.
- Type checker: Set a regex literal expression's type as `_StringProcessing.Regex<(Substring, DynamicCaptures)>`. `(Substring, DynamicCaptures)` is a temporary `Match` type that will help get us to an end-to-end working system. This will be replaced by actual type inference based a regex's pattern in a follow-up patch (soon).
- SILGen: Lower a regex literal expression to a call to `_StringProcessing.Regex.init(_regexString:)`.
- String processing runtime: Add `Regex`, `DynamicCaptures` (matching actual APIs in apple/swift-experimental-string-processing), and `Regex(_regexString:)`.

Upcoming:
- Build `_MatchingEngine` and `_StringProcessing` modules with sources from apple/swift-experimental-string-processing.
- Replace `DynamicCaptures` with inferred capture types.

37f16520e6 Prototype regex literal AST and emission
With `-enable-experimental-string-processing`,
start lexing `'` delimiters as regex literals (this
is just a placeholder delimiter for now). The
contents of which gets passed to the libswift
library, which can return an error string to be
emitted, or null for success.

The libswift side isn't yet hooked up to the Swift
regex parser, so for now just emit a dummy
diagnostic for regexes starting with quantifiers.

If successful, build an AST node which will be
emitted as an implicit call to an
`init(_regexString:)` initializer of an in-scope
`Regex` decl (which will eventually be a known
stdlib decl).

c57b80a3c8 Final walker cleanups
Instead of tracking the single-expression closures in a separate
structure and passing that in under the right conditions, it makes more
sense to simply set the 'Where' decl context to the single-expr closure
and use the correct declaration context to determine whether the context
is async. The reduces the number of variables that need to get plumbed
through to the actual unavailable-from-async check and simplifies the
actual check from figuring out whether we're in a single-expr closure or
in an async context.

8be85c09b9 [Sema] Have isValidTypeExprParent consider its child
With the introduction of the ArgumentList type,
argument expressions will be direct decedents of
call expressions, without an intermediate TupleExpr.
As such, we need to tweak isValidTypeExprParent to
consider the child expression such that `T(x)` is
permissible, but `x(T)` is not.

Change isValidTypeExprParent to take a child expr
parameter, and update its use in MiscDiagnostics
and PreCheckExpr. For PreCheckExpr, switch from a
stack to walking the parent directly, as a
stack-based approach would be a bit more fiddly in
this case, and walking the parents shouldn't be
expensive.

This should be NFC, I'm splitting it off from the
ArgumentList refactoring to make the rebasing there
a little more straightforward.
