Erik Eckstein 762e9c7882 Serialization: serialize if the module is a static library ...

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.
