Move the VecPair<A, B> data structure from NAK's ir.rs to the shared
compiler Rust crate so it can be reused by other backends.
The fields are private, and NAK's ir.rs (now in a different crate)
needs to read and mutate the inner Vecs. Add a_as_slice(..),
a_as_mut_slice(..), b_as_slice(..) and b_as_mut_slice(..), and update
NAK's SrcsAsSlice and DstsAsSlice impls to call them. Returning slices
keeps callers from changing the length of one side without the other,
which is what VecPair is built to prevent.

There are four depth first searches in cfg.rs. This adds a DFS
abstraction which we can later optimize.

Move the memstream code into common code. Other Rust code interfacing
with FILE pointers will find the memstream abstraction useful.
Most notably, pinning is actually enforced this time with PhantomPinned.
Add a .clang-format from a sibling dir (i.e.: compiler/nir) while we're
at it to keep things tidy.
