anv: Advertise larger heap sizes

Instead of just advertising the aperture size, we do something more
intelligent.  On systems with a full 48-bit PPGTT, we can address 100%
of the available system RAM from the GPU.  In order to keep clients from
burning 100% of your available RAM for graphics resources, we have a
nice little heuristic (which has received exactly zero tuning) to keep
things under a reasonable level of control.

anv: Add support for 48-bit addresses

This commit adds support for using the full 48-bit address space on
Broadwell and newer hardware.  Thanks to certain limitations, not all
objects can be placed above the 32-bit boundary.  In particular, general
and state base address need to live within 32 bits.  (See also
Wa32bitGeneralStateOffset and Wa32bitInstructionBaseOffset.)  In order
to handle this, we add a supports_48bit_address field to anv_bo and only
set EXEC_OBJECT_SUPPORTS_48B_ADDRESS if that bit is set.  We set the bit
for all client-allocated memory objects but leave it false for
driver-allocated objects.  While this is more conservative than needed,
all driver allocations should easily fit in the first 32 bits of address
space and keeps things simple because we don't have to think about
whether or not any given one of our allocation data structures will be
used in a 48-bit-unsafe way.

anv/blorp: Align vertex buffers to 64B

This fixes issues seen when adding support for full 48-bit addresses.
The 48-bit addresses themselves have nothing to do with it other than
that it caused the kernel to place buffers slightly differently so they
interacted differently with the caches.

anv: Query the kernel for reset status

When a client causes a GPU hang (or experiences issues due to a hang in
another client) we want to let it know as soon as possible.  In
particular, if it submits work with a fence and calls vkWaitForFences or
vkQueueQaitIdle and it returns VK_SUCCESS, then the client should be
able to trust the results of that rendering.  In order to provide this
guarantee, we have to ask the kernel for context status in a few key
locations.

such as textureSize(gsampler2DMS*) in SPIR-V.  Instead of trying to list
out all of the cases one at a time, just provide the default for all TXS

viewport scaled by that amount is still a subrange of [-32767, 32767].

The old code has a couple of issues:
1) It used scissor instead of viewport_scissor, potentially taking into
   account a viewport that is too small and therefore selecting a scale
   that is too large.
2) Merging the viewports isn't ideal, as for example viewports with

   while their union [0, 1001] only allows a scale of ~32.

The new code just determines the guardband per viewport and takes the minimum.

radv: fix interp at sample code.

Interp at sample needs to use the center, since the sample
positions it retrieves are relative to the center.

This fixes a bunch of CTS tests with multisample_interpolation.

radv: overhaul fragment shader sample positions.

The current code was broken, and I decided to redesign it instead.

This puts the sample positions for all samples into the queue
constant descriptor buffer after all the spill/ring descriptors.

It then uses a single offset register to point how far into the
samples the samples for num_samples are. This saves one user sgpr
and means we only generate the sample position data in the rare
single case where we need it currently.

This doesn't fix the failing CTS tests without the followup
fix.
