When we print types in the AST printer if for some reason we cannot find the
appropriate type to print or if the user explicitly asks, we fall back and use a
type repr instead.
This behavior causes a problem due to the implementation of sending results
using a sending type repr to communicate that the relevant function has a
sending result, but we actually do not use the sending type repr from that point
on. So as a result, in this fallback case, we put in one too many sending on the
result.

The option to print #ifs defaulted to "on", but was disabled in most of
the actual compiler inputs that mattered, and the results weren't ever
actually used. Remove the option so we never print #ifs.
Previously, the opaque types in patterns were printed using their full stable
reference which cannot be resolved when parsing a swiftinterface.

Minor fixes
Replace the existing C++ implementation of extractInlinableText with
a new implementation based on swift-syntax. It uses SwiftIfConfig to
remove inactive regions (with a special mode), and a new compiler-only
entrypoint in the library to remove comments and `#sourceLocation`.
Allow any declaration to be marked with `@unsafe`, meaning that it
involves unsafe code. This also extends to C declarations marked with
the `swift_attr("unsafe")` attribute.
Under a separate experimental flag (`DisallowUnsafe`), diagnose any
attempt to use an `@unsafe` declaration or any unsafe language feature
(such as `unowned(unsafe)`, `@unchecked Sendable`). This begins to
define a "safe" mode in Swift that prohibits memory-unsafe constructs.
Always add constraints, find fixes during simplify.
New separate fix for allow generic function specialization.
Improve parse heuristic for isGenericTypeDisambiguatingToken.
Degrade concrete type specialization fix to warning for macros.
Using init accessors from inlinable code requires `@usableFromInline`
annotation, which means that we need to print them in swift interfaces
and serialize them.
Although actor initializers can be classified as convenience initializers by
the internals of the compiler, they are not written that way in source and
should not be printed with the `convenience` keyword.

The reason why I am doing this is that consuming could cause no implicit
copy errors. Instead __owned will just potentially cause an error if
someone assigns into sending.
