Without TC, we'd get draw->count==0.. which is obviously not correct.
With TC we get random garbage for draw->count. Which turns into
exciting things like trying to allocate multi-gigabyte buffers for
tess param/factor buffers.
But we can just tell the CP to split up large tess draws, and put an
upper bound on the tess param/factor buffer sizes.

Since the last round of enhanced layout packing, it seems like this code
is no longer needed. This allows us to use the HANDLE_EMIT_BUILTIN()
macro, which simplifies things further.
It would have been incorrect anyway, because it's the only code that
uses the location directly as an index. All other locations multiplies
it by four first.

Since image stores can now compress and we can't track image stores
this also stops using predication for DCC decompression.
In GFX10 this was benchmarked to be faster. For GFX10.3 the microbenchmarks

For 16x16 we get 4 16x4 waves, which is bad for DCC image stores.
The workgroup size doesn't really matter for speed, the important
part is the number of waves, which should stay constant here.
(Though some optimization would be nice, but out of scope for this
patch)
The compute DCC compress shader still uses 16x16 due to functional
requirements (and we're sure it won't write with DCC compression ...)

We are providing a BO with the default attribute values for the
GL_SHADER_STATE_RECORD, that contains 16 vec4. Such default value for
each vec4 is (0, 0, 0, 1). As the attribute format could be int or
float, the "1" value needs to take into account the attribute format.
But in the practice, the most common case is all floats. So we create
one default attribute values BO assuming that all attributes will be
floats, and we store it at v3dv_device and only create a new one if a
int format type is defined. That allows to reduce the amount of BOs
needed.
Note that we could still try to reduce the amount of BOs used by the
pipelines if we create a bigger BO, and we just play with the
offsets. But as mentioned, that's not the usual, and would add an
extra complexity,so it is not a priority right now.
This makes the following test passing when disabling the pipeline

There is a similar check in _eglAddDRMDevice, however it will be
removed in a future commit to allow split render/display devices
to be properly added. We can't figure out whether we're on a split

The way we handle thrsw instructions is that we try to merge them
back into previously scheduled instructions to fill up its delay
slots. This is generally safe, because the thrsw won't happen until
after the delay slots, so we are not really changing the execution
order of the instructions and we just need to make sure we don't
violate a few specific restrictions.
If we have not managed to fill up all delay slots after doing this,
then we emit as many NOPs as needed to fill them. This is to ensure
that we don't schedule an instruction that needs to execute after the
thread switch before the thread switch happens. However, doing this
can lead to inefficient code, since some times the instructions we
schedule after a thrsw are indepdent of the thrsw and could be safely
executed in its delay slots.
This change removes the fixed NOP emission after a thrsw to fill
delay slots and instead adds code to ensure that our instruction
scheduling is aware of when it is scheduling instructions in the
delay slots of a previous thrsw to avoid selecting conflicting
instructions.
The only case were we still emit fixed NOPs is for the thread end that
we emit to terminate the program after scheduling all instructions
because we can't end the instruction stream before the thread end
is properly executed.
