Introducing new entry-points that can be used from both Driver and Frontend clients, using an intermediary new type: `DetailedMessagePayload`, when needed.
Starting at a crude -1000, each invocation primary input will get its own unique quasi-Pid.
Invocations with only one primary (non-batch) will get a real OS Pid.
The selection of the constant starting point matches what the driver does when outputting its parseable output.
Follow programming guidelines for these getters more closely and have them return a non-owning view of the underlying data instead of relying on callers to take const references to the copy that is returned here.
T *const does not prevent logically non-const accesses to the underlying data, it merely indicates that the pointer value itself is const. This modifier can be cast off by a copy, so it's not generally what you want here. Switch to const T * instead.
Adds a new frontend option
"-experimental-allow-module-with-compiler-errors". If any compilation
errors occur while generating the .swiftmodule, this mode will skip SIL
entirely and only serialize the (likey invalid) AST.
This existence of this option during generation is serialized into the
resulting .swiftmodule. Errors found in deserialization are only allowed
if it is set.
Primarily intended for IDE requests (eg. indexing and code completion)
to ensure robust cross-module results, despite possible errors.

The new message is:
"Please submit a bug report (https://swift.org/contributing/#reporting-bugs) and include the crash backtrace."
1. In crash logs we used to print a message which points to the llvm bug tracking page. Now it points to the swift.org bug tracking guidelines.
2. Use the same message in all compiler diagnostics which ask the user to file a bug report.

To help consolidate our various types describing imports, this commit moves the following types and methods to Import.h:
* ImplicitImports
* ImplicitStdlibKind
* ImplicitImportInfo
* ModuleDecl::ImportedModule
* ModuleDecl::OrderImportedModules (as ImportedModule::Order)
* ModuleDecl::removeDuplicateImports() (as ImportedModule::removeDuplicates())
* SourceFile::ImportFlags
* SourceFile::ImportOptions
* SourceFile::ImportedModuleDesc
This commit is large and intentionally kept mechanical—nothing interesting to see here.
Also perform the plumbing necessary to convince the rest of the compiler that they're just ordinary external dependencies. In particular, we will still emit these depenencies into .d files, and code completion will still index them.
Invert the responsibility of the entrypoint so that FrontendTool is directing the actual serialization work. The entrypoint now solely exists to construct a dependency graph.
While I'm here, prepare the way for serializing dependency graphs for modules by optimistically modeling a ModuleOrSourceFile input.
For now, force the clang-based actions to skip the end of the pipeline. This restores the previous behavior of the frontend, but may not be desirable in the long run. For example, one may want to dump clang stats after running an -emit-pch job, but that is impossible without forcing the end of the pipeline to be more tolerant of ObjCHeader/modulemap-only inputs.

Try to impose a simple structure that splits performing actions from the
pre and post-pipeline conditions. Wherever actions would take more than
a simple return, split them into functions. Refine functions that
perform effects to return status codes when they fail. Finally,
delineate functions that need semantic analysis from those that do not.
Overall this should be NFC.
To help solving rdar://67079780, this change allows swift-driver to configure scanner using additional
arguments passed down via the batch input JSON file for each module under scanning.
This scanning mode allows swift-driver to query module dependencies in a batch
and in a more granular way. In short term, it could help solve a problem that
clang module dependencies may vary if target triple changes. In a longer term,
we could break a holistic dependencies graph into smaller pieces for better caching
and reusing.
This change doesn't include the implementation of using the specified scanner
arguments to set up Clang dependencies scanner. It will come in later commits.
For the issue mentioned in rdar://67079780, swift-driver needs to run clang dependencies
scanner multiple times with different target triples for a Swift target. This patch adds
a new scanning action to generate the JSON file for a given clang module to accommodate
this requirement.
