util: unbreak endian detection on OpenBSD

Since cbee1bfb34274668a05995b9d4c78ddec9e5ea4c endian.h is unconditionally
used if available.

glibc has byte order defines with two leading underscores.  OpenBSD
has private defines with a single leading underscore in machine/endian.h
and public defines in endian.h with no underscore.

The code under the endian.h block did not check if symbols were
defined before equating them so '#if __BYTE_ORDER == __LITTLE_ENDIAN'
would turn into '#if 0 == 0' which is always true.

intel/nir: Rewrite the guts of lower_alpha_to_coverage

I have no idea how this pass ever worked.  I guess it worked ok on the
one or two piglit tests but the whole thing seemed very fragile.  It
makes a number of undocumented and unasserted assumptions and they
aren't always valid.  This rewrite makes a number of changes:

 1. It now properly handles the case where the gl_SampleMask write comes
    before the gl_FragColor or gl_FragData[0] write.

 2. It should early-exit faster because it now looks at bits in
    shader_info::outputs_written instead of looking for variables.

 3. Instead of the fragile variable lookup where we try to look the
    variable up by both location and driver_location and match, we just
    use the driver_location calculations used by brw_fs_nir.

 4. It asserts that the index parameter to store_output is a constant
    instead of silently failing if it isn't.

 5. We now actually assert the implicit assumption that the two writes
    are in the same block.  We go even further and assert that they are
    in the last block in the shader.

 6. In the case where 3 or fewer components of the output are written,
    we explicitly choose to leave the sample mask alone.

panfrost: Inline panfrost_vt_init

Again, we'd like to keep the routines filling out the postfix together,
and this has a single remaining caller (once for vertex then immediately
for tiler).

By keeping them together we can avoid uploading the shared
memory/framebuffer structures twice in a row, saving a bit of memory in
the process.

We also fix a bug where bit 2 of gl_enables is incorrectly set on
Bifrost.

panfrost: Don't call panfrost_vt_init for compute

Given we emit shared memory immediately after anyway, the function call
doesn't do anything but zero-initializing the payload and setting some
magic bits. We can do that ourselves at the call site.

panfrost: Remove postfix parameter from UBO upload

Need to signal push constants via a side channel. I tried to disentangle
this code, but there are a number of stacked issues here:

* We need to upload sysvals. Currently we prefix UBO #0 with sysvals,
  but this requires a memcpy() of the entire contents of UBO #0. We
  could create a synthetic UBO instead with sysvals at the end.

* We want to push uniforms/sysvals. Currently we push UBO #0 as much as
  we can, which pushes sysvals automatically by point 1.

* We want to optimize out f2f16(uniform). We don't currently handle
  this.

* We want to optimize out uniform-on-uniform/constant operations. Mesa
  doesn't currently have good support for this.

The real solution will look something like:

* Create a separate UBO for sysvals.

* Let the compiler allocate push constant space as it sees fit ("copy
  word 12:15 of UBO 1 to word 2:3 of push constant space, as fp16").

* Somehow handle uniform folding when NIR gains support.

For now, let's not block the depostfixening.

anv: simplify push constant emissions

Instead of allocating a push constant buffer per stage from the
dynamic state pool, we can use the same one for all stages.

We can do this because the push constant data is supposed to be
identical of all stages. Even if vkCmdPushConstants() allows to update
chunks of the push constant data differently per stage, this valid
usage guarantees that any chunk of push constant data used be 2
different stages must be identical :

   "For each byte in the range specified by offset and size and for
    each push constant range that overlaps that byte, stageFlags must
    include all stages in that push constant range’s
