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.

i965/fs: Always provide a default LOD of 0 for TXS and TXL

We already provide a default LOD for textureQueryLevels and texture() on
non-fragment stages.  However, there are more cases where one is needed
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
and TXL operations.  This fixes a shader validation error in the new
Sascha deferredmultisampling demo which uses textureSize(gsampler2DMS).

We want the guardband_x/y to be the largerst scalars such that each
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
   boundaries [0,1] and [1000, 1001] would allow a guardband scale of ~30k,
   while their union [0, 1001] only allows a scale of ~32.

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