Add a SPIR-V target-specific intrinsic for creating handles, which is used for lowering HLSL resources types like RWBuffer. `llvm/lib/TargetParser/Triple.cpp`: SPIR-V intrinsics use "spv" as the target prefix, not "spirv". As far as I can tell, this is the first one that is used via the `CGBuiltin` codepath, which relies on `getArchTypePrefix`, so I've corrected it here. `clang/lib/Basic/Targets/SPIR.h`: When records are laid out in the lowering from AST to IR, they were incorrectly offset because these Pointer attributes were defaulting to 32.
