egl/android: Add DRM node probing and filtering

This patch both adds support for probing & filtering DRM nodes
and switches away from using the GRALLOC_MODULE_PERFORM_GET_DRM_FD
gralloc call.

Currently the filtering is based just on the driver name,
and the desired name is supplied using the "drm.gpu.vendor_name"
Android property.

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: 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/lower_samplers: split out _legacy version for deref chains

To simplify the transition, and make things bisectable, split out a
legacy copy or lower_samplers.  This way the i965 and gallium drivers
can independently switch over to deref instructions.

Since the lower_samplers_as_deref pass is only used by gallium drivers,
it can be converted in lock-step with moving the lower_deref_instrs
pass, and so does not need a corresponding _legacy clone.

This legacy pass will be removed in a future commit.
