These commits set up the skeleton for SPIR-V to LLVM dialect conversion. I created SPIR-V to LLVM pass, registered it in Passes.td, InitAllPasses.h. Added a pattern for `spv.BitwiseAndOp` and tests for it. Integer, float and vector types are converted through LLVMTypeConverter. Differential Revision: https://reviews.llvm.org/D81100
