ParameterEncodingTy

using llvm::AbstractCallSite::CallbackInfo::ParameterEncodingTy = SmallVector<int, 0>

For direct/indirect calls the parameter encoding is empty.

If it is not, the abstract call site represents a callback. In that case, the first element of the encoding vector represents which argument of the call site CB is the callback callee. The remaining elements map parameters (identified by their position) to the arguments that will be passed through (also identified by position but in the call site instruction).

NOTE that we use LLVM argument numbers (starting at 0) and not clang/source argument numbers (starting at 1). The -1 entries represent unknown values that are passed to the callee.
