This patch adds a pass to replace calls to vector intrinsics (i.e., LLVM intrinsics operating on vector operands) with calls to a vector library.

Currently, calls to LLVM intrinsics are only replaced with calls to vector libraries when scalar calls to intrinsics are vectorized by the Loop- or SLP-Vectorizer.

With this pass, it is now possible to replace calls to LLVM intrinsics already operating on vector operands, e.g., if such code was generated by MLIR. For the replacement, information from the TargetLibraryInfo, e.g., as specified via `-vector-library` is used.
