aco: Add README which explains about what ACO is and how it works.
...
This is based on an early summary written by Daniel, but updated to
reflect the current state of ACO and reworded to better fit the format.
Also added is a table which details what SW stages correspond to what
HW stages on each HW generation.

...
The old "readme" is not really a readme but rather just
a bunch of notes with our findings about the GCN/RDNA ISA.

aco: fix a hazard with v_interp_* and v_{read,readfirst}lane_* on GFX6
...
It's required to insert 1 wait state if the dst VGPR of any v_interp_*
is followed by a read with v_readfirstlane or v_readlane to fix GPU
hangs on GFX6. Note that v_writelane_* is apparently not affected.
This hazard isn't documented anywhere but AMD confirmed it.
This fixes a GPU hang with the texturemipmapgen Sascha demo on GFX6.

aco/gfx10: Fix VcmpxExecWARHazard mitigation.
...
The SOPP instruction shouldn't have a definition, and its block
should be set to -1 in order to prevent it from being recognized
as a branch.
Also fix a typo in the readme.
