radv/winsys: fix creating the BO list for virtual buffers

When the number of unique BO is 0, we optimize the list creation
by copying all buffers of the current CS directly into it. But
this is only valid if the CS doesn't have virtual buffers,
otherwise they are not added and hw might report VM faults.

This fixes VM faults with:

and prevents boot due to SIGSEGV MAPERR crash related to unproper handling
of drm_gralloc drm FD in new droid_open_device() path.

Problem is due to c7bb82136b ("egl/android: Add DRM node probing and filtering")

To avoid the crash the former existing working droid_open_device() is restored,
renamed droid_open_device_drm_gralloc() and kept within HAVE_DRM_GRALLOC braces.

Tested with mesa-dev and mesa 18.2 branch and oreo-x86 bootanimation

NOTE: Definition of enum{} for GRALLOC_MODULE_PERFORM_GET_DRM_FD
is not necessary and it's actually causing a redefinition building error,

freedreno/ir3: create all inputs in first block

create_input()/create_input_compmask() should take the ctx as arg,
rather than block, to enforce that all inputs are created in the first
block, so that RA sees them as live at the start of the shader.

freedreno: a2xx: ir2 update

this patch brings a number of changes to ir2:

 fd2_program/fd2_compiler and is necessary to implement optimization passes
-ir2 now has separate vector/scalar instructions. this will make it easier
 to implementing scheduling of scalar+vector instructions together. dst_reg
 is also now seperate from src registers instead of a single list
-ir2 now implements register allocation. this makes it possible to compile
 shaders which have more than 64 TGSI registers
-ir2 now implements the following optimizations: removal of IN/OUT MOV
 instructions generated by TGSI and removal of unused instructions when

-ir2 now allows full 8-bit index for constants

radv: Add on-demand compilation of built-in shaders.

In environments where we cannot cache, e.g. Android (no homedir),
ChromeOS (readonly rootfs) or sandboxes (cannot open cache), the
startup cost of creating a device in radv is rather high, due
to compiling all possible built-in pipelines up front. This meant
depending on the CPU a 1-4 sec cost of creating a Device.

For CTS this cost is unacceptable, and likely for starting random
apps too.

So if there is no cache, with this patch radv will compile shaders
on demand. Once there is a cache from the first run, even if
incomplete, the driver knows that it can likely write the cache
and precompiles everything.

Note that I did not switch the buffer and itob/btoi compute pipelines
to on-demand, since you cannot really do anything in Vulkan without
them and there are only a few.

This reduces the CTS runtime for the no caches scenario on my
threadripper from 32 minutes to 8 minutes.

i965/nir: Use the nir copy of shader_info to handle gl_PatchVerticesIn

Instead of using the copy of shader_info stored in gl_program, it now
uses the one in nir_shader. This is needed for SPIR-V because the
info.tess.tcs_vertices_out is filled in via _mesa_spirv_to_nir which
happens much later than with a GLSL shader. The copy of shader_data in
gl_program is only updated later via brw_shader_gather_info but that
is too late.

For GLSL this shouldn't create any problems because the nir copy of
the shader_info is immediately copied from the gl_program in
glsl_to_nir.
