[llvm] [IR] Avoid call to deprecated PointerType::getUnqual (NFC)\ (PR #134609)

[Mats Jun Larsen via llvm-commits]

https://github.com/junlarsen created https://github.com/llvm/llvm-project/pull/134609

Should keep MSVC quiet as noticed by @rksimon in #134517.

Assertions have been copied over from PointerType::get in order to not silently change invariants with this call.
