The star is one shader in glmark2's terrain (drops 16% of its
instructions), but there are also wins in mupen64plus and glb2.7.

vc4: Flip the switch to run the GLSL compiler optimization loop once.

This has almost no effect on shader-db:

total instructions in shared programs: 92572 -> 92611 (0.04%)
instructions in affected programs:     4486 -> 4525 (0.87%)

Looking at 2 of the 7 different shaders that were hurt (all of which were
in mupen64), they all appear to be just differences in order of
instructions at the NIR level.

The advantage is that this should significantly reduce time in the compiler.

i965: Unbind deleted shaders from brw_context, fixing malloc heisenbug.

Applications may delete a shader program, create a new one, and bind it
before the next draw.  With terrible luck, malloc may randomly return a
chunk of memory for the new gl_program that happened to be the exact
same pointer as our previously bound gl_program.  In this case, our
logic to detect new programs in brw_upload_pipeline_state() would break:

      if (brw->vertex_program != ctx->VertexProgram._Current) {
         brw->vertex_program = ctx->VertexProgram._Current;
         brw->ctx.NewDriverState |= BRW_NEW_VERTEX_PROGRAM;
      }

Because the pointer is the same, we'd think it was the same program.
But it could be wildly different - a different stage altogether,
different sets of resources, and so on.  This causes utter chaos.

As unlikely as this seems, I believe I hit this when running a subset
of the CTS in a loop, in a group of tests that churns through simple
programs, deleting and rebuilding them.  Presumably malloc uses a
bucketing cache of sorts, and so freeing up a gl_program and allocating
a new one fairly quickly causes it to reuse that memory.

The result was that brw->vertex_program->info.num_ssbos claimed the
program had SSBOs, while brw->vs.base.prog_data.binding_table claimed
that there were none.  This was crazy, because the binding table is
calculated from info.num_ssbos - the shader info appeared to change
between shader compile time and draw time.  Careful use of watchpoints
revealed that it was being clobbered by rzalloc's memset when building
an entirely different program...

Fortunately, our 0xd0d0d0d0 canary for unused binding table entries
caused us to crash out of bounds when trying to upload SSBOs, or we
may have never discovered this heisenbug.

Fixes crashes in GL45-CTS.compute_shader.sso-case2 when using a hacked
cts-runner that only runs GL45-CTS.compute_shader.s* in EGL config ID 5
at 64x64 in a loop with 100 iterations.

i965/sync: Implement fences based on Linux sync_file

This patch implements a new type of struct brw_fence, one that is based
struct sync_file.

This completes support for EGL_ANDROID_native_fence_sync.

* Background

  Linux 4.7 added a new file type, struct sync_file. See

    commit 460bfc41fd52959311ed0328163f785e023857af
    Author:  Gustavo Padovan <gustavo.padovan@collabora.co.uk>
    Date:    Thu Apr 28 10:46:57 2016 -0300
    Subject: dma-buf/sync_file: de-stage sync_file headers

  A sync file is a cross-driver explicit synchronization primitive. In a
  sense, sync_file's relation to synchronization is similar to dma_buf's
  relation to memory: both are primitives that can be imported and
  exported across drivers (at least in theory).

i965/sync: Rename brw_fence_insert()

Rename to brw_fence_insert_locked(). This is correct because the fence's
mutex is effectively locked, as all callers are also *creators* of the
fence, and have not yet returned the new fence.

This reduces noise in the next patch, which defines and uses
brw_fence_insert(), an unlocked variant.

i965/sync: Fail sync creation when batchbuffer flush fails

Pre-patch, brw_sync.c ignored the return value of
intel_batchbuffer_flush().

When intel_batchbuffer_flush() fails during eglCreateSync
(brw_dri_create_fence), we now give up, cleanup, and return NULL.

When it fails during glFenceSync, however, we blindly continue and hope
for the best because there does not exist yet a way to tell core GL that
sync creation failed.
