Otherwise, queries might return invalid data because they used
the same offsets as NGG streamout.

The kernel keeps returning -ENOMEM if multiple processes allocate GDS,
this always happen while running VKCTS. This solution is loosely based
on RadeonSI, except that it includes a timeout of 1s to exit the loop.

NGG streamout lowering requires nir_shader::num_outputs to be set to
the total number of outputs in order to compute the pervertex LDS size
correctly. This is wasting LDS memory but it's currently the only viable
solution.
This fixes a bunch of dEQP-VK.transform_feedback.* failures.

If the size is passed through CmdBindTransformFeedback() uses that.
This partially fixes dEQP-VK.transform_feedback.simple.multiquery_1
by reporting the correct number of primitives written (the computation
is based on the buffer size). There is still a bug around GDS offsets
that will be fixed later.

According to the AMD registers database, SAMPLE_STREAMOUTSTATS no
longer exists on GFX11. This fixes primitives generated query if only
the NGG path is used. Tested on GFX10.3 by forcing NGG everywhere.

This is actually not necessary because we compile and upload binaries
directly from libraries with GPL. This introduced random double free

NIR has two implementations of lower_idiv, keyed on the
imprecise_32bit_lowering flag. This flag is misleading: the results when
setting this flag "imprecise", they're completely wrong for some values.
If a backend has a native implementation of umul_high, the correct path
isn't that much more expensive. If it doesn't, it's substantially slower
for highp integer divison... but in practice, non-constant highp integer
division is pretty rare.
After a painful migration of the tree, this code path has no more users.
Remove it so nobody else gets the bright idea of using it again.
