[llvm] [IR] Remove deprecated typed-pointer creation APIs (PR #212812)

[Marc Auberer via llvm-commits]

https://github.com/marcauberer created https://github.com/llvm/llvm-project/pull/212812

Removes `PointerType::get(Type*, unsigned)`, `PointerType::getUnqual(Type*)`, and `Type::getPointerTo(unsigned)`, the last typed-pointer-creation leftovers from the opaque pointers migration. All three have been marked deprecated for a while and have no remaining in-tree callers; every caller already uses the LLVMContext-taking overloads.

Subject: [PATCH] [IR] Remove deprecated typed-pointer creation APIs

Removes PointerType::get(Type*, unsigned), PointerType::getUnqual(Type*),
and Type::getPointerTo(unsigned), the last typed-pointer-creation leftovers
from the opaque pointers migration. All three have been marked deprecated
for a while and have no remaining in-tree callers; every caller already
uses the LLVMContext-taking overloads.
