My concern is that the integer returned from `omp_init_allocator` is a **value**. This means it is (usually) only known at runtime. Whereas **attributes** are known at compile time.

Previously for the built-in allocators an attribute made sense because the mapping from the keyword to the integer is always known. This isn't true for user-defined allocators because the handle is returned from a runtime call. I'm worried this will make lowering code difficult.
