[Distributed] Adjust interface of `swift_distributed_execute_target`
Since this is a special function, `calleeContext` doesn't point to
a direct parent but instead both parent context (uninitialized)
and resume function are passed as last arguments which means that
`callContext` has to act as an intermediate context in call to accessor.

Opened archetypes can be created in the constraint system, and the
existential type it wraps can contain type variables. This can happen
when the existential type is inferred through a typealias inside a
generic type, and a member reference whose base is the opened existential
gets bound before binding the generic arguments of the parent type.
However, simplifying opened archetypes to replace type variables is
not yet supported, which leads to type variables escaping the constraint
system. We can support cases where the underlying existential type doesn't
depend on the type variables by canonicalizing it when opening the
existential. Cases where the underlying type requires resolved generic
arguments are still unsupported for now.
Form opened archetype types based on an interface type and existential
type, rather than assuming all OpenedArchetypeType instances only
represent the root. Sink the UUID, existential type, and actual creation
of the opened archetype into the opened generic environment, so we
consistently only create new archetype instances from the generic
environment. This slims down OpenedArchetypeType and makes it work
similarly to the other archetype kinds, as well as generalizing it
to support nested types.
Sink the existential type and UUID of an
We don't need lazy creation of generic environments for opaque archetypes,
because they don't do much work up front. Make it eager, so we can
move away from delayed generic environment creation entirely.
All non-nested archetype types already have a generic environment field,
and nested archetype types will need one soon anyway on their way to
irrelevance, so sinking the field doesn't isn't a net loss. While
here, isolate the code that lazily creates and caches the environment,
because only one subclass uses it (for opened archetypes) and I had
inadvertently broke caching there recently.
This may be the cause of the instability we've been seeing on the bots
here. If a type variable is used as the pattern type across allocation
arenas, we may incorrectly reuse a cache entry and it could be
substituted a second time for a bogus type.

Applies swift-experimental-string-processing#68 in regex literal type inference. Regex literals with captures will have type `Regex<Tuple{n}<Substring, {Captures...}>>`. This is a temporary thing that allows us to define generic constraints on captures. We will switch back to native tuples once we have variadic generics.
The refactoring that moved the substitution of the outer environment
into an opaque type archeptype into the generic environment eliminated
the need for the bound signature entirely, so remove it.
Teach `GenericEnvironment` how to lazily create opaque type archetypes,
performing the contextual substitutions as required but without
building the "bound" generic signature until required. To get here,
augment `GenericEnvironment` with knowledge of the purpose of the
environment, whether it is for normal cases (any signature), an opened
existential type, or an opaque type. For opaque types, store the
opaque type declaration and substitution map, which we also use to
uniquely find the generic environment. Among other things, this
ensures that different opaque type archetypes within the same opaque
type declaration are properly sharing a generic environment, which
wasn't happening before.
As a small step toward moving away from having a bespoke generic
environment for each OpaqueTypeArchetypeType, create the types
without the generic environment and only build it lazily.
This patch introduces new diagnostics to the ClangImporter to help
explain why certain C, Objective-C or C++ declarations fail to import
into Swift. This patch includes new diagnostics for the following entities:
- C functions
- C struct fields
- Macros
- Objective-C properties
- Objective-C methods
In particular, notes are attached to indicate when any of the above
entities fail to import as a result of refering an incomplete (only
forward declared) type.
The new diangostics are hidden behind two new flags, -enable-experimental-clang-importer-diagnostics
and -enable-experimental-eager-clang-module-diagnostics. The first flag emits diagnostics lazily,
while the second eagerly imports all declarations visible from loaded Clang modules. The first
flag is intended for day to day swiftc use, the second for module linting or debugging the importer.
Generalize the implementation of opaque type declarations to maintain
the "ordinal", which represents a particular "some" utterance in a
structural opaque type, throughout more of the compiler.
The ordinal value for a given "some" matches with the index of the
corresponding generic parameter in the opaque type declaration's
generic signature. To properly be able to determine the ordinal for a
given "some" type representation, retain all of the "some" type
representations in the `OpaqueTypeDecl` (using trailing storage), so
we can map them to the proper generic parameter and ordinal later on.
This reverts commit a67a0436f7, reversing
changes made to 9965df76d0.
This commit or the earlier commit this commit is based on (#40531) broke the
incremental bot.
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 `'...'`.
A pack type looks a lot like a tuple in the surface language, except there
is no way for the user to spell a pack. Pack types are created by the solver
when it encounters an apply of a variadic generic function, as in
```
func print<T...>(_ xs: T...) {}
// Creates a pack type <String, Int, String>
print("Macs say Hello in", 42, " different languages")
```
Pack types substituted into the variadic generic arguments of a
PackExpansionType "trip" the pack expansion and cause it to produce a
new pack type with the pack expansion pattern applied.
```
typealias Foo<T...> = (T?...)
Foo<Int, String, Int> // Forces expansion to (Int?, String?, Int?)
```
When looking for a Swift module on disk, we were scanning all module search paths if they contain the module we are searching for. In a setup where each module is contained in its own framework search path, this scaled quadratically with the number of modules being imported. E.g. a setup with 100 modules being imported form 100 module search paths could cause on the order of 10,000 checks of `FileSystem::exists`. While these checks are fairly fast (~10µs), they add up to ~100ms.
To improve this, perform a first scan of all module search paths and list the files they contain. From this, create a lookup map that maps filenames to the search paths they can be found in. E.g. for
```
searchPath1/
Module1.framework
searchPath2/
Module1.framework
Module2.swiftmodule
```
we create the following lookup table
```
Module1.framework -> [searchPath1, searchPath2]
Module2.swiftmodule -> [searchPath2]
```

The new type, called ExistentialType, is not yet used in type resolution.
Later, existential types written with `any` will resolve to this type, and
bare protocol names will resolve to this type depending on context.
- 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.
This cleans up 90 instances of this warning and reduces the build spew
when building on Linux. This helps identify actual issues when
building which can get lost in the stream of warning messages. It also
helps restore the ability to build the compiler with gcc.
