radeonsi: Fix crash on shaders using MSAA image load/store

The value returned by tgsi_util_get_texture_coord_dim() does not
account for the sample index. This means image_fetch_coords() will not
fetch it, leading to a null deref in ac_build_image_opcode() which
expects it to be present (the return value of ac_num_coords() *does*
include the sample index).

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

Commit 92f01fc5f914 ("i965: Emit VF cache invalidates for 48-bit
addressing bugs with softpin.") tried to only emit the VF invalidate if
the high bits changed, but it accidentally always set need_invalidate to
true; causing it to emit unconditionally emit the pipe control before

tegra: Treat resources with modifiers as scanout

Resources created with modifiers are treated as scanout because there is
no way for applications to specify the usage (though that capability may
be useful to have in the future). Currently all the resources created by
applications with modifiers are for scanout, so make sure they have bind
