Restore comptags to be bitmap-allocated, like they were before we had
the buddy allocator.
The new buddy allocator introduced by
e99aa2485f8992eabe3556f3ebcb57bdc8ad91ff (originally
6ab2e0c49cb79ca68d2f83f1d4610783d2eaa79b) is fine for the big VAs, but
unsuitable for the small compbit store.
This commit reverts partially the combination of the above commit and
also one after it, 86fc7ec9a05999bea8de320840b962db3ee11410, that fixed
a bug which is not present when using a bitmap. With a bitmap allocator,
pruning the extra allocation necessary for user-mapped mode is possible,
so that is also restored.
The original generic bitmap allocator is not restored; instead, a
comptag-only allocator is introduced.

Implement a new buddy allocation scheme for the GPU's VA space.
The bitmap allocator was using too much memory and is not a scaleable
solution as the GPU's address space keeps getting bigger. The buddy
allocation scheme is much more memory efficient when the majority
of the address space is not allocated.
The buddy allocator is not constrained by the notion of a split
address space. The bitmap allocator could only manage either small
pages or large pages but not both at the same time. Thus the bottom
of the address space was for small pages, the top for large pages.
Although, that split is not removed quite yet, the new allocator
enables that to happen.
The buddy allocator is also very scalable. It manages the relatively
small comptag space to the enormous GPU VA space and everything in
between. This is important since the GPU has lots of different sized
spaces that need managing.
Currently there are certain limitations. For one the allocator does
not handle the fixed allocations from CUDA very well. It can do so
but with certain caveats. The PTE page size is always set to small.
This means the BA may place other small page allocations in the
buddies around the fixed allocation. It does this to avoid having
large and small page allocations in the same PDE.
