Use only the SWIFT_COMPILER_VERSION macro to check for swiftmodules
being written by the same compiler that reads it. In practice, it's the
macro used for release builds of the compiler.

Since I am beginning to prepare for adding real move only types to the language,
I am renaming everything that has to do with copyable types "move only wrapped"
values instead of move only. The hope is this reduces/prevents any confusion in
between the two.
The ObjCMethodLookupTable for protocols was not being serialized and rebuilt on load, so NominalTypeDecl::lookupDirect() on selectors was not working correctly for deserialized types. Correct this oversight.
When a synchronous, actor-isolated declaration witnesses an
asynchronous, not-similarly-isolated requirement, emit an actor hop
within the witness thunk to ensure that we properly enter the context
of the actor.
Fixes#58517 / rdar://92881539.
Swiftc port of https://github.com/apple/llvm-project/pull/4207.
This introduces a new flag, `-file-prefix-map` which can be used
instead of the existing `-debug-prefix-map` and `-coverage-prefix-map`
flags, and also remaps paths in index information currently.
llvm/llvm-project d0262c2394f46bb7da2a75529413d625c70908e5 added a new
default bool param to the two constructors in `SmallVectorMemoryBuffer`.
Since `options.OutputPath` is a `const char *` and that can be promoted
to a `bool`, the constructor being called was changed to the first
constructor (with a default buffer name) - promotion is preferred over
conversion.
Convert the various output paths to a `StringRef` - all their uses
converted to `StringRef` anyway. Also specify the default parameter in
order to maintain the old behaviour, which didn't require a null
terminator.
- Add a `[reflection]` bit to `alloc_box` instructions, to indicate that a box
should be allocated with reflection metadata attached.
- Add a `@captures_generics` attribute to SILLayouts, to indicate a type layout
that captures the generic arguments it's substituted with, meaning it can
recreate the generic environment without additional ABI-level arguments, like
a generic partial application can.
Write the real module name for XRefs in swiftmodule files instead of the
exported module name, from `export_as` declarations in module maps.
Swiftmodule files are internal details now, they should represent the
truth.
We keep using the exported module name for the extensions lookup table
as clients should still use the exported name. However we may need to
write both alternatives in the lookup table in the future if extensions
can't be found from clients not importing the exported as module.

This ensures that opened archetypes always inherit any outer generic parameters from the context in which they reside. This matters because class bounds may bind generic parameters from these outer contexts, and without the outer context you can wind up with ill-formed generic environments like
<τ_0_0, where τ_0_0 : C<T>, τ_0_0 : P>
Where T is otherwise unbound because there is no entry for it among the generic parameters of the environment's associated generic signature.
