fixes #140321 Specifically it fixes ` error: Cannot create BufferLoad operation: Invalid overload type` https://hlsl.godbolt.org/z/dTq4q7o58 but no new DML shaders are building. This change now exposes #144747. The change does two things it adds i64 support for intrinsic expansion for the `dx_resource_load_typedbuffer`, and `dx_resource_store_typedbuffer` intrinsics. It also lets loaded typedbuffers crash more gracefully because of ` auto *EVI = cast<ExtractValueInst>(U);` is now a `dyn_cast` and `llvm_unreachable`.
