1b9b2f9046 agx: Condition writeout ops on already being emitted
There's a lot of r/e waiting here, but will be needed for ld_tile. Match
the Metal blob.

28801b4849 agx: Add forward optimizing pass for fmov
Explain the ideas behind our SSA-based optimizer (inspired by ACO's,
thank you to Daniel Schuermann for discussing this with me in the
context of Bifrost), and implement the subset needed to propagate
abs/neg through.

2470a080d2 agx: Stub NIR backend compiler
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.)
