built-in.

+ cir.func @abort()

+ // A function with internal linkage.
+ cir.func internal @count(%x: i64) -> (i64)

There's a 1-to-1 correspondance between this and the `dso_local` representation
in LLVM IR, and we are able to model the computation of this flag after the
same computation in classic codegen. I don't think there's benefit in trying to
generalize this as an intermediate state when we'll need to recreate it when
lowering to LLVM IR anyway.
