We add a lowering pass for nir intrinsics. This pass can replace nir
intrinsics with driver specific nir lower code.
We lower the gl_LocalInvocationIndex intrinsic based on a uniform
which is loaded with a thread specific ID.
We also lower the gl_LocalInvocationID based on
gl_LocalInvocationIndex.
v2:
* Create variable during lowering pass. (Ken)
v3:
* Don't create a variable, but instead just insert an intrisic call
to load a uniform from the allocated location. (Jason)
v4:
* Don't run this pass if thread_local_id_index < 0

This thread ID uniform will be used to compute the
gl_LocalInvocationIndex and gl_LocalInvocationID values.
It is important for this uniform to be added in the last push constant
register. fs_visitor::assign_constant_locations is updated to make
sure this happens.
The reason this is important is that the cross-thread push constant
registers are loaded first, and the per-thread push constant registers
are loaded after that. (Broadwell adds another push constant upload
mechanism which reverses this order, but we are ignoring this for
now.)
v2:
* Add variable in intrinsics lowering pass
* Make sure the ID is pushed last in assign_constant_locations, and
that we save a spot for the ID in the push constants
v3:
* Simplify code based with Jason's suggestions.

v4:
* Force thread_local_id_index to -1 for now, and have
fs_visitor::setup_cs_payload look at thread_local_id_index. This
enables us to more easily cut over from the old local ID layout to
the new layout, as suggested by Jason.

We will chain multiple chunks together and will keep pointers to the older

This avoids allocating giant IBs from the outset, especially for CE and DMA.
Since we now limit max_dw only by the size that the buffer happens to be
(which, due to the buffer cache, can be even larger than the rounded-up size
we request), the new function amdgpu_ib_max_submit_dwords controls when we
submit an IB.
With this change, we effectively never flush prematurely due to the CE IB,
after an initial warm-up phase.
