This makes it more like `AllSets::{gen,kill}_set`, removes the need for
a bunch of bitset range computations, and removes the need for `Bits`.
It's marginally less efficient, because we have to allocate one bitset
per basic block instead of one large shared bitset, but the difference
is negligible in practice.
The `Buf` vs. non-`Buf` distinction is no longer necessary, and the nastiest code in this file can be removed. To minimize this patch, `IdxSet` is made a typedef of `IdxSetBuf`. The next patch will remove this typedef.
Now that the `Buf` vs. non-`Buf` distinction has been removed, it makes sense to drop the `Buf` suffix and use the shorter names everywhere.
