nir/opt_loop_unroll: Fix has_nested_loop handling

In 87839680c0a48, 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:

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.

These exist to convert between different types of boolean values.  In
particular, we want to use these for uniform and shared memory
operations where we need to convert to a reasonably sized boolean but we
don't care what its format is so we don't want to make the back-end
insert an actual i2b/b2i.  In the case of uniforms, Mesa can tweak the
format of the uniform boolean to whatever the driver wants.  In the case
of shared, every value in a shared variable comes from the shader so
it's already in the right boolean format.

The new boolean conversion opcodes get replaced with mov in
lower_bool_to_int/float32 so the back-end will hopefully never see them.
However, while we're in the middle of optimizing our NIR, they let us
have sensible load_uniform/ubo intrinsics and also have the bit size
conversion.

nir: Collect if shader uses cross-invocation or indirect I/O.

The following new fields are added to tess shader info:

* `tcs_cross_invocation_inputs_read`
* `tcs_cross_invocation_outputs_read`

These are I/O masks that are a subset of inputs_read and outputs_read
and they contain which per-vertex inputs and outputs are read
cross-invocation.

Additionall, the following new fields are added to shader_info:

* `inputs_read_indirectly`
* `outputs_accessed_indirectly`
* `patch_inputs_read_indirectly`
* `patch_outputs_accessed_indirectly`

These new fields can be used for optimizing TCS in a back-end compiler.
If you can be sure that the TCS doesn't use cross-invocation inputs
or outputs, you can choose a different strategy for storing VS and TCS
outputs. However, such optimizations might need to be disabled when
the inputs/outputs are accessed indirectly due to backend limitations,
so this information is also collected.

Example: RADV currently has to store all VS and TCS outputs in LDS, but
for shaders when only inputs and/or outputs belonging to the current
invocation ID are used, it could skip storing these in LDS entirely.

freedreno/ir3/ra: add def/use iterators

Decouple the messy logic of figuring out vreg names defined/used by an
instruction from the logic of what to do about it by introducing
iterators.  There is still *some* array vs ssa special casing in
ra_block_compute_live_ranges(), but less than before.  And this will
avoid introducing a second copy of the def/use logic in a following
patch which uses the liveranges to calculate the maximum # of live
values (which is the optimal target for max physical register window
to round-robin within).

freedreno/ir3/ra: drop extending output live-ranges

This is no longer needed as we create meta:collect instructions in the
end block, which achieves the same result.

freedreno/ir3/ra: add helper to map name to array

For vreg names that refer to arrays rather than SSA values, this is the
counterpart to name_to_instr().

freedreno/ir3/ra: fix target register calculation

Account for the # of regs an instruction writes, and fix an off-by-one.

(We are about to replace this with calculating the register target using
the live-ranges, but in debugging that it was useful to assert() if it
chose a higher target.)

freedreno/ir3/ra: add helper to map name to instruction

Extract out a helper from the select_reg callback.  And include all the
instructions in the hashtable, not just SFU.  This will be useful in the
following commits.

freedreno/ir3: add bary_ij as src for meta:tex_prefetch

This way RA doesn't have to special case it in use/def accounting..

This gets rid of an extra level of split/collect, which shouldn't be
needed.  And interferes with scheduler trying to put tex-prefetches
after inputs but before other instructions.  (Otherwise it would have
to figure out which split/collects need to go before the tex-prefetch)
