"unknown_2" field is actually a size of instruction that branch
points to. If it's set to a smaller size than actual instruction
branch behavior is not defined (and it usually wedges the GPU).
Fix it by setting this field correctly.

This corresponds to what the GC3000 blob does. The USED / UNUSED enums are
wrong, at least for GC2000/GC3000.
Without this the 3rd texture component is not interpolated correctly (flat?)
in the following test (and others):
dEQP-GLES2.functional.texture.mipmap.cube.generate.rgba8888_nicest
Strangely, when the texture is sampled from OpenGL it works correctly,
the problem only shows up for sampling by gallium/blitter. This fixes other
cube map tests which use util_blitter_blit.

The rs alignment doesn't have to be multiplied by # of pixel pipes.
This works on GC2000 which doesn't have the SINGLE_BUFFER feature.
This fixes some cubemaps (NPOT / small mipmap levels) because aligning by 8
breaks the expected alignment of 4 for tiled format. We don't want to mess
with the alignment of tiled formats.

Mali job dependency graphs, at least for GLES3.0, have the special
property that a given node will only have at most a single dependent.
This allows us to efficiently precompute the dependent array and
replace an inner loop's O(N) search with an O(1) lookup, bringing the
algorithmic complexity of scoreboarding from O(N^2) to O(N).

Until now we have always been emitting our scoreboard locks on the last thread
switch to improve parallelism. We did this by emitting our last thread switch
right before our tlb writes at the very end of the program, where we know that
we are outside control flow.
Unfortunately, this strategy is not valid when we have tlb color reads too, as
these will happen before this point in the program and can happen inside
control flow.
To fix this we always emit a thread switch before the first tlb load and if we
see additional thread switches after that point, we change the strategy to lock
on the first thread switch.
v2: change the solution so it is expected to work in more scenarios (Eric).

We were failing to flag the program dirty when it changed. Also, we
were unnecessarily setting key->input_vertices for SINGLE_PATCH mode,
which would reduce program cache hits. Only set it if needed.
Right now, all keys have two things in common: a program string ID and a
sampler_prog_key_data. I'd like to add another thing or two and need a
place to put it. This commit adds a new brw_base_prog_key struct which
contains those two common bits.

The reason for doing this is two-fold:
1. These passes are likely to be shared with the Bifrost compiler
Therefore, we don't want to restrict them to Midgard
2. The coding style is different (NIR-style vs Panfrost-style)
The NIR passes are candidates for moving upstream into
compiler/nir, so don't block that off for stylistic reasons
