Alternative noncopyable switch design based on expression kind.
...
If an expression refers to noncopyable storage, then default to performing
a borrowing switch, where `let` bindings in patterns borrow out of the
matched value. If an expression refers to a temporary value or explicitly
uses the `consume` keyword, then perform a consuming switch, where
`let` bindings take ownership of corresponding parts of the matched value.
Allow `_borrowing` to still be used to explicitly bind a pattern variable
as a borrow, with no-implicit-copy semantics for copyable values.

stdlib: Adopt @_disallowFeatureSuppression(NoncopyableGenerics).

This prevents some re-declaration errors when building the standard library
from its `.swiftinterface` with older compilers.

stdlib: Make typed throws ABI placeholders properly @usableFromInline.
...
Functions that are used in public `@inlinable` function bodies can't be marked
`@_spi` nor can they be made obsolete. Also, they must retain `rethrows` so
that use of these entry points from other `rethrows` functions is accepted.
Builds on https://github.com/apple/swift/pull/72365 . Once we no longer have to
support pre-`$TypedThrows` compilers, all of this can be reverted.

[embedded] Compile-time (literal) KeyPaths for Embedded Swift
...
Enable KeyPath/AnyKeyPath/PartialKeyPath/WritableKeyPath in Embedded Swift, but
for compile-time use only:
- Add keypath optimizations into the mandatory optimizations pipeline
- Allow keypath optimizations to look through begin_borrow, to make them work
even in OSSA.
- If a use of a KeyPath doesn't optimize away, diagnose in PerformanceDiagnostics
- Make UnsafePointer.pointer(to:) transparent to allow the keypath optimization
to happen in the callers of UnsafePointer.pointer(to:).

Replace two reduces with explicit loops in SIMD implementations. ( #72423 )
...
* Replace two `reduce`s with explicit loops in SIMD implementations.
`reduce` has enough machinery that it pushes us over some inlining thresholds before optimizations happen, resulting in much worse codegen for String breadcrumbs. So a nice pickup there, but also generally applicable to other code as well.

stdlib: enable a check for a special case in Array.append(contentsOf:)
...
The check for the special case if the sequence is an Array was disabled in embedded swift.
It can be enabled because we now remove the cast after specialization.
Saves some code size when appending one array to another array.
