This is the initial version of a buildable SIL definition in libswift. It defines an initial set of SIL classes, like Function, BasicBlock, Instruction, Argument, and a few instruction classes. The interface between C++ and SIL is a bridging layer, implemented in C. It contains all the required bridging data structures used to access various SIL data structures.
