egl/android: Add DRM node probing and filtering
This patch both adds support for probing & filtering DRM nodes

Currently the filtering is based just on the driver name,

egl/android: #ifdef out flink name support
Maintaining both flink names and prime fd support which are provided by
2 different gralloc implementations is problematic because we have a
dependency on a specific gralloc implementation header.
This mostly disables the dependency on the gralloc implementation and
headers. The dependency on GRALLOC_MODULE_PERFORM_GET_DRM_FD remains for
now, but the definition is added locally to remove the header
dependency.
drm_gralloc support can be enabled by setting
BOARD_USES_DRM_GRALLOC=true in BoardConfig.mk.

r600/sb: give the scheduler more margin to find valid instructions groups
For instruction sequences that change the address register with every load
the current limit to bail out of the scheduler and reject the optimisation
was too tight, i.e. it was expected that at least one pending instruction

Give the scheduler more margin to sort out these load sequences by allowing

r600/sb: fix rotated register in while loop
This patch is based on
https://lists.freedesktop.org/archives/mesa-dev/2018-February/185805.html
Dave Airlie:
"A bunch of CTS tests led me to write
tests/shaders/ssa/fs-while-loop-rotate-value.shader_test
which r600/sb always fell over on.
GCM seems to move some of the copies into other basic blocks,
if we don't allow this to happen then it doesn't seem to schedule
them badly.
Everything I've read on SSA/phi copies say they have to happen
in parallel, so keeping them in the same basic block seems like
a good way to keep some of that property."
This patch differs from the one proposed by Dave in that it only adds
the NF_DONT_MOVE flag to copy_move instructions that are created by split_phi*
and that are located in loops.
Fixes piglit: tests/shaders/ssa/fs-while-loop-rotate-value.shader_test
(no regressions in the shader set). It also fixes all failing tests from
dEQP-GLES3.functional.shaders.loops.*

nir,spirv: Rework function calls
This commit completely reworks function calls in NIR. Instead of having
a set of variables for the parameters and return value, nir_call_instr
now has simply has a number of sources which get mapped to load_param
intrinsics inside the functions. It's up to the client API to build an
ABI on top of that. In SPIR-V, out parameters are handled by passing
the result of a deref through as an SSA value and storing to it.
This virtue of this approach can be seen by how much it allows us to
delete from core NIR. In particular, nir_inline_functions gets halved
and goes from a fairly difficult pass to understand in detail to almost
trivial. It also simplifies spirv_to_nir somewhat because NIR functions
never were a good fit for SPIR-V.
Unfortunately, there is no good way to do this without a mega-commit.
Core NIR and SPIR-V have to be changed at the same time. This also
requires changes to anv and radv because nir_inline_functions couldn't
handle deref instructions before this change and can't work without them
after this change.

spirv: Allow pointers to have a deref at the base
Previously, pointers fell into two categories: index/offset for UBOs,
SSBOs, etc. and var + access chain for logical pointers. This commit
adds another logical pointer mode that's deref + access chain.
It's tempting to think that we can just replace variable-based pointers
with deref-based or at least replace the access chain with a deref
chain. Unfortunately, there are a few sticky bits that prevent this:
1) We can't return deref-based pointers from OpVariable because those
opcodes may come outside of a function so there's no place to emit
the deref instructions.
2) We can't always use variable-based pointers because we may not
always know the variable. (We do now, but he upcoming function
rework will take that option away.)
3) We also can't replace the access chain struct with a deref. Due to
the re-ordering we do in order to handle loop continues, the derefs
we would emit as part of OpAccessChain may not dominate their uses.
We normally fix this up with nir_repair_ssa but that generates phi
nodes which we don't want in the middle of our deref chains.
All in all, we have no real better option than to support partial access
chains while also re-emitting the deref instructions on the spot.

spirv: Make push constants an offset-based pointer
Push constants have been a weird edge-case for a while in that they have
explitic offsets but we've been internally building access chains for
them. This mostly works but it means that passing pointers to push
constants through as function arguments is broken. The easy thing to do
for now is to just treat them like UBOs or SSBOs only without a block
index. This does loose a bit of information since we no longer have an
accurate access range and any indirect access will look like it could
read the whole block. Unfortunately, there's not much we can do about
that. Once NIR derefs get a bit more powerful, we can plumb these
through as derefs and be able to reason about them again.
