This commit removes the support for typed pointers from the LLVM dialect. Typed pointers have been deprecated for a while and thus this removal was announced in a PSA: https://discourse.llvm.org/t/psa-removal-of-typed-pointers-from-the-llvm-dialect/74502 This change includes: - Changing the ` LLVMPointerType` - Removing remaining usages of the builders and the now removed element type - Fixing assembly formats that require fully qualified pointer types - Updating ODS pointer constraints
