1bc56dcc11 [stdlib] Mark some parameters @_nonEphemeral 
These include the pointer-to-pointer and pointer-to-buffer-pointer
initialiser parameters amongst a couple of others, such as
`Unmanaged.fromOpaque`, and the source for the `move[...]` family of
methods.

88630e8ea3 [stdlib] AutoreleasingUnsafeMutablePointer: use typed pointers rather than UnsafeRawPointer 
This improves code generation in -Onone mode. (UnsafeRawPointer.load/.storeBytes isn’t @_transparent and it doesn’t get specialized in unoptimized builds.)

6a92bb9e2e [stdlib] AutoreleasingUnsafeMutablePointer: eliminate questionable pointer use 
AutoreleasingUnsafeMutablePointer is pointing to a +0 reference, but in its pointee property’s getter/setter implementations, it is loading the pointer into regular Unsafe[Mutable]Pointers. Those are assuming that the addressed memory contain a +1 reference, which can mislead the compiler into doing optimizations that aren’t valid.

Change the getter/setter implementations so that they use UnsafeRawPointer and load/store Unmanaged values instead. As long as Unmanaged.passUnretained(_:) and Unmanaged.takeUnretainedValue() do the right thing, then AutoreleasingUnsafeMutablePointer won’t have issues, either. (This boils down to ensuring that loading a strong reference out of an unmanaged(unsafe) value works correctly.)

460a5213fc Revert "[stdlib] AutoreleasingUnsafeMutablePointer: Switch subscripts to _read accessors" 
This was an ABI break, since it didn't make it into 5.0. Using _read here is unimportant, so we're just going to revert rather than try being fancy.

This reverts commit 04586e3916.

6e6aae8d61 Mark all _unconditionallyBridgeFromObjectiveC functions as @_effects(readonly) 
This enables removal of those bridging calls for dead parameters. Read-only lets the optimizer remove such a call if the result is not used.
Note that "readonly" means: no observable write operations. It's okay to allocate and initialize new objects.

c31033c525 [+0-all-args] Make _bridgeAnythingNonVerbatimToObjectiveC() take its parameter at +1. 
This hoists out the retain into Swift code from the casting runtime and along a
few paths in the runtime allows us to eliminate a dynamic retain release.
