If there are modifiers only used by pseudo instructions, not the real

This may be a temporary issue, depending whether ISA.xml and the IR get split

In the TGSI backend the loads got emitted at use time, while the NIR
backend was emitting the loads at load intrinsic time.  By sinking the

Fix 'error C4576: a parenthesized type followed by an initializer
list is a non-standard explicit type conversion syntax' errors by
declaring an actual variable and returning it in
vk_image_view_subresource_range().

All those MSVC/c++ related-constraints are quite annoying to be honest,
but it looks like the D3D12 headers have been updated to plain C
recently, which will allow us to write the driver in C, and hopefully
get all this sort of issues behind us.

was ineffectual in the scenario where a ubo pointsize was needed on
the first time a non-precompiled shader was used after being the not-last
vertex stage:

* have vs+gs -> gs precompiles with pointsize lowering -> gs constants get updated
* remove gs -> vs was precompiled without pointsize lowering -> vs constants broken

now just do a quick check as in st_atom_shader.c and set the flag manually to
ensure the update is done correctly every time

Rob Clark 802f4da5ee freedreno/drm: Add virtio backend 
Add a new backend to enable using native driver in a VM guest, via a new
virtgpu context type which (indirectly) makes host kernel interface
available in guest and handles the details of mapping buffers to guest,
etc.

Note that fence-fd's are currently a bit awkward, in that they get
signaled by the guest kernel driver (drm/virtio) once virglrenderer in
the host has processed the execbuf, not when host kernel has signaled
the submit fence.  For passing buffers to the host (virtio-wl) the egl
context in virglrenderer is used to create a fence on the host side.
But use of out-fence-fd's in guest could have slightly unexpected
results.  For this reason we limit all submitqueues to default priority
(so they cannot be preepmted by host egl context).  AFAICT virgl and
venus have a similar problem, which will eventually be solveable once we
have RESOURCE_CREATE_SYNC.

With userspace fences, if we know definitely that the buffer is idle
(which implies that it is not shared with other processes, etc), then
skip the ioctl.

Rob Clark 9bcc983256 freedreno/drm: Add fd_bo_upload() 
There are some buffers that we mmap just to write to them a single time.
Add the possibility of the drm backend to provide an alternate upload
path to avoid these mmap's.

Rob Clark 115518ec35 freedreno/drm: Add FD_BO_SHARED hint 
With the virtio backend we will need to pass an extra flag when
allocating buffers that will be shared cross-device (such as with
virtio-wl for passing between host and guest)
