SIL: Add linkage and calling conv to SILFunctions. Move AbstractCC into SILType and make it an attribute of SILTypes for functions. Add a ConvertCCInst to represent calling convention conversions. Give SILFunctions a linkage attribute. Add logic to SILGen to calculate these attributes for SILConstants based on their attached decls. IRGen doesn't use these new attributes yet. I'll hook that up when I move mangling over. Swift SVN r4886
