Alyssa Rosenzweig 902f99a45d pan/bi: Expand out FMA conversion opcodes 
There are a *lot* of them, with lots of symmetry we can exploit to
simplify the packing logic (but not entirely). Let's add the
corresponding header structs/defines, although we don't actually poke
the disassembler at this stage.

Alyssa Rosenzweig 0f65f00a0d panfrost: Move pan_bo to root panfrost 
Now that its Gallium dependencies have been resolved, we can move this
all out to root. The only nontrivial change here is keeping the
pandecode calls in Gallium-panfrost to avoid creating a circular
dependency between encoder/decoder. This could be solved with a third
drm folder but this seems less intrusive for now and Roman would
probably appreciate if I went longer than 8 hours without breaking the
Android build.

Rob Clark 1b3aefad46 freedreno/log: avoid duplicate ts's 
In cases where `fd_log()`/`fd_log_stream()` are called multiple times
back-to-back, just use the timestamp of the first trace.

This seems to avoid some occasional GPU hangs I was seeing with logging
enabled.  Although not exactly sure the reason for the hangs.  (Looks
like GPU hangs *after* all the cmdstream is processed, according to
crashdec.)

Jason Ekstrand b113170559 nir/opt_loop_unroll: Fix has_nested_loop handling 
In 87839680c0, a very subtle mistake was made with the CFG walking
recursion.  Instead of setting the local has_nested_loop variable when
process child loops, has_nested_loop_out was passed directly into the
process_loop_in_block call.  This broke nested loop detection heuristics
and caused loop unrolling to run massively out of control.  In
particular, it makes the following CTS test compile virtually forever:

dEQP-VK.spirv_assembly.instruction.graphics.16bit_storage.struct_mixed_types.uniform_buffer_block_geom

Eric Anholt 92afe94d28 freedreno: Work around UBWC flakiness. 
In trying to track down the new failure in #2670, I found that I could get
the flaky test set down to 4 tests, and dropping any remaining test
wouldn't trigger the failure (a bad 8x4 block in the middle of
dEQP-GLES3.functional.fbo.msaa.4_samples.r16f's render target).  Disabling
gmem or bypass didn't help, and adding lots of CCU flushing didn't help.
What did help was disabling blitting, or this memset to initialize the
UBWC area after we (presumably) pull a BO out of the BO cache.  My guess
is that the 2D blitter can't handle some rare set of state in the flags
buffer and emits some garbage.

I've run 8 gles3 and 7 gles31 runs with this branch now so hopefully I've got the4 right set of flakes marked for removal.
