This encapsulates the bitset's word size and word count, which means
consumers no longer need to be careful about word count. Users of the old
apis for writing expressions on bit sets should migrate to the new expression
API.

The new api doesn't require allocations for intermediate values in
expressions. It also has tests, which is nice because eg. the previous
implementation of the `&` operator was broken.

This is extremely difficult to use correctly for bitsets of
different sizes. Also, nobody uses it. Remove the footgun.

`ninja test` wasn't actually running these tests, I guess because the
target name was duplicated in meson. Fix this so the tests actually run.

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.

This adds explicit lifetimes to any function which looks at a NIR
object, fishes a pointer out of it, and returns a reference. The theory
of operation for these NIR wrappers is that everything holds an implicit
shared reference to the whole shader and so this is safe to do as long
as no one ever has a mut reference to anything. However, since these
methods are turning pointers into references, it's a lot more obvious
what's going on if we have explicit lifetimes.
