virgl: Always assume that ORIGIN_UPPER_LEFT and PIXEL_CENTER* are supported

The driver must support at least one of

  PIPE_CAP_TGSI_FS_COORD_ORIGIN_UPPER_LEFT
  PIPE_CAP_TGSI_FS_COORD_ORIGIN_LOWER_LEFT

and one of

  PIPE_CAP_TGSI_FS_COORD_PIXEL_CENTER_HALF_INTEGER
  PIPE_CAP_TGSI_FS_COORD_PIXEL_CENTER_INTEGER

otherwise glsl_to_tgsi will fire an assert.

ORIGIN_UPPER_LEFT is the default convention, and is supported by
all mesa drivers, hence it seems reasonable to always report the caps
to be enabled.  On gles ORIGIN_LOWER_LEFT is generally not supported,
so we rely on the caps reported by the host that depend on whether we
run on an GL or an EGL host.

For PIXEL_CENTER it is completely host driver dependend on what is
supported, and since we do not report the actual host driver capabilities
it is best to mark both as supported, this is how it works for a GL
host too.

radv: Handle GFX9 merged shaders in radv_flush_constants()

This was not previously handled correctly. For example,
push_constant_stages might only contain MESA_SHADER_VERTEX because
only that stage was changed by CmdPushConstants or
CmdBindDescriptorSets.

In that case, if vertex has been merged with tess control, then the
push constant address wouldn't be updated since
pipeline->shaders[MESA_SHADER_VERTEX] would be NULL.

Use radv_get_shader() instead of getting the shader directly so that
we get the right shader if merged. Also, skip emitting the address
redundantly - if two merged stages are set in push_constant_stages
this change would have made the address get emitted twice.

util: Add a virtual memory allocator

This is simple linear-walk first-fit allocator roughly based on the
allocator in the radeon winsys code.  This allocator has two primary
functional differences:

 1) It cleanly returns 0 on allocation failure

 2) It allocates addresses top-down instead of bottom-up.

The second one is needed for Intel because high addresses (with bit 47
set) need to be canonicalized in order to work properly.  If we allocate
bottom-up, then high addresses will be very rare (if they ever happen).
We'd rather always have high addresses so that the canonicalization code
gets better testing.

intel/fs: Add explicit last_rt flag to fb writes orthogonal to eot.

When using multiple RT write messages to the same RT such as for
dual-source blending or all RT writes in SIMD32, we have to set the
"Last Render Target Select" bit on all write messages that target the
last RT but only set EOT on the last RT write in the shader.
Special-casing for dual-source blend works today because that is the
only case which requires multiple RT write messages per RT.  When we
start doing SIMD32, this will become much more common so we add a
dedicated bit for it.
