intel/fs: Split instructions low to high in lower_simd_width

Commit 0d905597f fixed an issue with the placement of the zip and unzip
instructions.  However, as a side-effect, it reversed the order in which
we were emitting the split instructions so that they went from high
group to low instead of low to high.  This is fine for most things like
texture instructions and the like but certain render target writes
really want to be emitted low to high.  This commit just switches the
order back around to be low to high.

This patch is based on

Dave Airlie:

 "A bunch of CTS tests led me to write

  Everything I've read on SSA/phi copies say they have to happen
  in parallel, so keeping them in the same basic block seems like

vulkan: add VK_EXT_display_control [v10]

This extension provides fences and frame count information to direct

vblank sequence and nanosecond resolution.

v2: Remove DRM_CRTC_SEQUENCE_FIRST_PIXEL_OUT flag. This has
    been removed from the proposed kernel API.

    Add NULL parameter to drmCrtcQueueSequence ioctl as we

v3: Adapt to pthread clock switch to MONOTONIC

    Declare variables at first use, eliminate extra whitespace between

    Use wsi_rel_to_abs_time helper function to convert relative
    timeouts to absolute timeouts without causing overflow.

Suggested-by: Jason Ekstrand <jason.ekstrand@intel.com>
v6:
    Change WSI fence wait function to return VkResult instead of
    bool. This makes the meaning of the return value easier to
    understand, and allows for the indication of failure.

    Also change the WSI fence wait function to take only absolute
    timeouts and not provide an option for a relative timeout. No
    users wanted relative timeouts, and it's simpler if that option
    isn't available.

    Terminate the DPMS property loop once we've found the property.

    Assert that the fence hasn't already been destroyed in
    wsi_display_fence_destroy.

    Rearrange the event handler function order in the file to place
    routines in an easier to find order.

v7:

v8:
    Use wsi->alloc in register_display_event so that callers
    don't have to dig out an allocator for us.

v9:

Suggested-by: Jason Ekstrand <jason.ekstrand@intel.com>
v10:
    Use wsi->alloc if none provided in wsi_display_fence_alloc.

    Now that drivers are expected to pass the allocator argument
    straight through from the application, we need to check those

anv: Support wait for heterogeneous list of fences [v3]

Handle the case where the set of fences to wait for is not all of the
same type by either waiting for them sequentially (waitAll), or
polling them until the timer has expired (!waitAll). We hope the
latter case is not common.

While the current code makes sure that it always has fences of only
one type, that will not be true when we add WSI fences. Split out this
refactoring to make merging that clearer.
