c1257eb4ef Runtimes: introduce SwiftOnoneSupport 
The main goal for now is to have this building, with little
concern about matching the build flags used currently.

Keep it disabled by default on Apple platforms.

ed4863f76c Sema: don't use llvm::StringSwitch for runtime function names 
Using `llvm::StringSwitch` with this many cases causes clang to crash due to a stack overflow.

956bd10be4 Prevent shadowing of unavailable member impls 
Typically, access control denies access to member implementations, so the imported interface decl will be used instead. However, in contexts that permit direct access to stored properties—such as accessors, inits, and deinits—their member implementations are accessible; the compiler then relies on a shadowing rule favoring Swift decls over ObjC decls to eliminate the imported interface decl.

However, there are many rules that are higher-priority than the Swift vs. ObjC decls one. In particular, a recent change to availability checking in #77886 caused a higher-priority rule to begin eliminating member implementations which belonged to unavailable extensions. This caused regressions in projects using `@objc @implementation` with classes that are unavailable in Mac Catalyst.

Introduce a fairly high-priority shadowing rule that favors a member implementation over its interface when both are present (i.e. when direct access to storage is permitted).

Fixes rdar://143582383.

53553fa172 Fix swift::areUsesWithinValueLifetime for guaranteed values 
To find if all the uses are within a guaranteed value, we should find all borrow introducers.

swift::findOwnershipReferenceAggregate looks only through forwarding operations with single operands.

For simplicity, continue using swift::findOwnershipReferenceAggregate, but return false when it does
not find a borrow introducer.

    In Xcode16 it is not supported.
