Alyssa Rosenzweig 8066ef9d30 agx: Port minifloat tests to GTest
These tests predate using GTest in the compiler. Now that we do, we'd like to
have the tests together so they run regularly.

Alyssa Rosenzweig 6b22bbab36 agx: Add validation pass
For now, just check that we didn't botch the structure of the block,
since this just bit me.

Alyssa Rosenzweig c712043b9c agx: Unit test parallel copy lowering
It's pretty tricky.

Alyssa Rosenzweig 4fc023ed42 agx: Use a transfer graph for parallel copies
Lifted from ir3. Algorithm is the same; the data structures and interface are
lightly modified to decouple from ir3's IR.

Sequentializing parallel copies after RA is tricky. ir3's implementation works
well enough, so I use that one.

Original implementation by Connor Abbott.

Alyssa Rosenzweig 7d38bcb7ee agx: Use pseudo ops for mov/not/and/xor/or
Rather than using builder magic (implicitly lowered on emit), add actual pseudo
operations (explicitly lowered before encoding). In theory this is slower, I
doubt it matters. This makes the instruction aliases first-class for IR prining
and machine inspection, which will make optimization passes easier to write.

Alyssa Rosenzweig 3d8c2f2693 agx: Add unit test infrastructure
Lifted from Bifrost. Add some basic optimizer tests (they pass!) to show the
compiler is ready to be unit tested. Given we can't have hardware CI for Asahi
yet -- and dEQP is still pretty janky -- unit testing should prove quite useful.

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.

Alyssa Rosenzweig 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.)
