This commit adds support for normalizing integer types as vendor
extended types for cross-language LLVM CFI/KCFI support with other
languages that can't represent and encode C/C++ integer types.

This will help with providing cross-language CFI support with the Rust
compiler. For more information about LLVM CFI/KCFI and cross-language
LLVM CFI/KCFI support for the Rust compiler, see the design document in
the tracking issue rust-lang/rust#89653.
