If the `-static` option is specified, store that in the generated
swiftmodule file. When de-serializing, recover this information in the
representative SILModule.
This will be used for code generation on Windows. It is the missing
piece to allow static linking to function properly. It additionally
opens the path to additional optimization on ELF-ish targets - GOT, PLT
references can be avoided when the linked module is known to be static.

This allows library authors to pass down a project version number so that library users can conditionally
import that library based on the available version in the search paths.

Introduce a new compiler flag `-module-abi-name <name>` that uses the
given name as the ABI name for the module (rather than the module's
name in source code). The ABI name impacts name mangling and metadata.
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.

* Add properties to ModuleFile which holds information from the control
block.
* 'ExtendedValidationInfo' parameter for 'ModuleFileSharedCore::load()'
cannot be 'nullptr'. Make it non-defaulted Rvalue reference.
'ModuleInterfacePath' is passed as 'StringRef' that memory used to
reside in ASTContext. But 'ModuleFileSharedCore' should be 'ASTContext'
independent. So copy it using its own allocator.
The difference with `ModuleFile` is that `ModuleFileSharedCore` provides immutable data and is independent of a particular ASTContext.
It is designed to be able to be shared across multiple `ModuleFile`s of different `ASTContext`s in a thread-safe manner.
