ad8b0f3397 [Sema] Allow @_section/@_used in concrete generic context (#75222) 
Allow `@_section` and `@_used` to be used in fully constrained extensions.

This aligns with the existing behavior of static properties of generic types. The following is valid:

```swift
extension Array where Element == Int {
  static let specificConstant = 41
}
```

However, adding `@_section` or `@_used` to the above property, will result in an error diagnostic.

This change updates the logic of `@_section`/`@_used` to allow their use when the generic context is fully concrete.

d755e90236 NCGenerics: limit field metadata heuristic 
We have had a heuristic that lets you reflect fields of types, where
the field's type is conditionally Copyable, despite the reflection
infrastructure always copying a field. That heuristic was added to allow
ubiquitous types like Optional in the stdlib to continue to be
reflected, even if the Optional at runtime really isn't Copyable.

As a consequence, we were also allowing reflection of fields containing
user-defined conditionally copyable types, when that's unsafe for no
real benefit, yielding runtime crashes!

I think in that case it's better to fall-back on the non-crashy case of
reflection seeing it as the EmptyTupleType, which isn't inhabited, so it
won't try to copy the field and instead basically skip-over it until a
future runtime supports the reflection safely.

So, this patch limits the dangerous reflection to only stdlib-defined
types, until Mirror and friends are updated.

76bb266624 NCGenerics: fix runtime demangling strategy 
We generally should use the open-coded, metadata function "accessor"
strategy when targeting older runtimes, but if the type is part of
the stdlib, assume the runtime demangler will produce correct
metadata, as the retrofitting of Optional, etc, was done Carefully.

9b1a82d9ec [IRGen] Add direct error return support for async functions 
rdar://129359370

Second part of direct error support. This implements direct errors for async functions. Instead of always returning typed errors indirectly, we are returning them directly when possible.

01a90cc99b Support nil completions in @objcImpl async methods 
An async @objc method only checks if its completion handler parameter is null if ClangImporter forces it to. This is fine for @objc with a generated header, because the generated header always declares the parameter _Nonnull, but clients ignore that annotation and pass nil anyway often enough that for @objc @implementation, we ought to be defensive.

We can achieve this by simply making the completion handler’s type Optional—SILGen already looks for this and knows what to do when it sees it.

Fixes rdar://130527373.
