agx: Implement some shader-db stats
...
Instructions, bytes, and registers -- this should hold us over until we
can reverse the underlying uarch and get proper cycle estimations.

A fork of the Bifrost compiler, tailored to AGX. nir_register support is
removed, as I want to use an SSA-based allocator for AGX. (There are no
VLIW-like requirements and extremely limited vector semantics, so we can
use an ACO approach with ease.)
