Introduce the experimental feature `ParserDiagnostics`, which emits
diagnostics from the new Swift parser *first* for a source file. If
that produces any errors, we suppress any diagnostics emitted from the
C++ parser.
Establish the relationship for generated sources, whether for macro
expansions or (via a small stretch) replacing function bodies with
other bodies, in the source manager itself. This makes the information
available for diagnostic rendering, and unifies a little bit of the
representation, although it isn't used for much yet.
Introduce a new behavior when printing references to modules with an
`export_as` definition. Use the `export_as` name in the public swiftinterface
and the real module name in the private swiftinterface.
This has some limits but should still be an improvement over the current
behavior. First, the we use the `export_as` names only for references to clang
decls, not Swift decls with an underlying module defining an `export_as`.
Second, we always print the `export_as` name in the public swiftinterface,
even in the original swiftinterface file when the `export_as` target is likely
not know, so that generated swiftinterface is still broken.
This behavior is enabled by the flags `-enable-experimental-feature ModuleInterfaceExportAs`
or the `SWIFT_DEBUG_USE_EXPORTED_MODULE_NAME_IN_PUBLIC_ONLY` env var. We may
consider turning it on by default in the future.

Introduces a concept of a dependency scanning action context hash, which is used to select an instance of a global dependency scanning cache which gets re-used across dependency scanning actions.
`getValue` -> `value`
`getValueOr` -> `value_or`
`hasValue` -> `has_value`
`map` -> `transform`
The old API will be deprecated in the rebranch.
To avoid merge conflicts, use the new API already in the main branch.

Prepare to accept the `ipi` argument to the `-library-level` flag. IPI
stands for Internal Programming Interface and would describe a module
that's not to be distributed outside of its project.
In the future, the compiler could use that information to report when a
distributed module (api or spi) imports publicly a module that's not
distributed.

`getValue` -> `value`
`getValueOr` -> `value_or`
`hasValue` -> `has_value`
`map` -> `transform`
This change does not cover all uses of the old API. Other warnings are worked around in llvm by https://github.com/apple/llvm-project/pull/5618
