Fixes a false alarm in case of recursive calls with different type parameters.
For example:
```
protocol P {
associatedtype E: P
}
func noRecursionMismatchingTypeArgs1<T: P>(_ t: T.Type) {
if T.self == Int.self {
return
}
noRecursionMismatchingTypeArgs1(T.E.self)
}
```
This is a value operation that can work just fine on lowered types,
so there's no need to carry along a formal type. Make the value/address
duality clearer, and enforce it in the verifier.
The definition of `DefautlActorImpl` changed in https://github.com/swiftlang/swift/pull/73998. This change reflects those changes on to RemoteInspection's platform independent definition.
The Error enum synthesized declarations, e.g. the struct and its static accessors, should generally appear to be identical to the underlying Clang definitions. There are some specific use cases where the synthesized declarations are necessary though.
I've added an option for USR generation to override the Clang node and emit the USR of the synthesized Swift declaration. This is used by SwiftDocSupport so that the USRs of the synthesized declarations are emitted.

The module name changes the symbol mangling, and also causes
TBDGen to emit linker directives. To separate out these two
behaviors, introduce a terrible hack. If the module name
contains a semicolon (`;`), the part before the semicolon
is the module name for mangling, and the part after the
semicolon is the module name for linker directives.
If there is no semicolon, both module names are identical,
and the behavior is the same as before.
Expand the special-cased ASTWalker behavior for folded SequenceExprs
such that we always walk the folded expression when available. This
ensures that we don't attempt to add the same node multiple times
when expanding ASTScopes during pre-checking.

Factor out `ConstraintSystem::getExplicitCaughtErrorType` from
`getCaughtErrorType`. Then use this for the contextual
type for a `throw` syntactic element.

The builtin’s current is signature is:
```
(Any.Type, Any.Type) -> Bool
```
This needs to be changed to this:
```
(any (~Copyable & ~Escapable).Type, any (~Copyable & ~Escapable).Type) -> Bool
```
This requires a bit of support work in AST synthesis.

The body of a function has to be re-analyzed for every call
site of the function, which is very expensive and if the
body is not changed would produce the same result.
This takes about ~10% from swift-syntax overall build time
in release configuration.
