9c53b80ff9 glsl: Minor cleanups after previous commit
I think it's more clear to only call emit_access once.  The only
difference between the two calls is the value of size_mul used for the
offset parameter... but you really have to look at it to be sure.

The s/is_64bit/is_double/ change is because there are no int64_t or
uint64_t matrix types.

88f5588f77 glsl/linker: Optimize swizzles again after linking
Without this, the SPIR-V generator has to deal with a bunch of junk
like:

    (swiz z (swiz xxx (swiz x (var_ref packed:binormal.z,light_dir))))

It seems better to cull that stuff out than to add code to deal with
it.  The problem is the way swizzles to and from scalars have to be
handled in SPIR-V.

f98a2768ca mesa: Add new fast mtx_t mutex type for basic use cases
While modern pthread mutexes are very fast, they still incur a call to an
external DSO and overhead of the generality and features of pthread mutexes.
Most mutexes in mesa only needs lock/unlock, and the idea here is that we can
inline the atomic operation and make the fast case just two intructions.
Mutexes are subtle and finicky to implement, so we carefully copy the
implementation from Ulrich Dreppers well-written and well-reviewed paper:

  "Futexes Are Tricky"
  http://www.akkadia.org/drepper/futex.pdf

We implement "mutex3", which gives us a mutex that has no syscalls on
uncontended lock or unlock.  Further, the uncontended case boils down to a
cmpxchg and an untaken branch and the uncontended unlock is just a locked decr
and an untaken branch.  We use __builtin_expect() to indicate that contention
is unlikely so that gcc will put the contention code out of the main code
flow.

A fast mutex only supports lock/unlock, can't be recursive or used with
condition variables.  We keep the pthread mutex implementation around as
for the few places where we use condition variables or recursive locking.
For platforms or compilers where futex and atomics aren't available,
simple_mtx_t falls back to the pthread mutex.

The pthread mutex lock/unlock overhead shows up on benchmarks for CPU bound
applications.  Most CPU bound cases are helped and some of our internal
bind_buffer_object heavy benchmarks gain up to 10%.

6a72eba755 mesa: rework how we free gl_shader_program_data
When I introduced gl_shader_program_data one of the intentions was to
fix a bug where a failed linking attempt freed data required by a
currently active program. However I seem to have failed to finish
hooking up the final steps required to have the data hang around.

Here we create a fresh instance of gl_shader_program_data every
time we link. gl_program has a reference to gl_shader_program_data
so it will be freed once the program is no longer active.

a16dc04ad5 i965: properly initialize brw->cs.base.stage to MESA_SHADER_COMPUTE
This has a bit of a surprising effect:

For the render pipeline, the upload_sampler_state_table atom emits
3DSTATE_BINDING_TABLE_POINTERS_XS.  It tries to avoid this for compute:

   if (GEN_GEN >= 7 && stage_state->stage != MESA_SHADER_COMPUTE) {
      /* Emit a 3DSTATE_SAMPLER_STATE_POINTERS_XS packet. */
      genX(emit_sampler_state_pointers_xs)(brw, stage_state);
   } ...

However, we were failing to initialize brw->cs.base.stage, so it was
left as 0 (MESA_SHADER_VERTEX), causing this condition to break.  We
then emitted 3DSTATE_SAMPLER_STATE_POINTERS_VS in GPGPU mode, when
trying to upload CS samplers.  Nothing good can come of this.

Found by inspection while debugging a GPU hang.  Jordan believes this
helps the Deus Ex: Mankind Divided benchmark mode's stability when
running with shader cache.

CXX11_CXXFLAGS.

The test only does a very shallow check of c++11 support, i.e. it tests
whether the define  __cplusplus >= 201103L to confirm language support
by the compiler, and it checks whether the header <tuple> is available
to test the availability of the c++11 standard library.

A make file conditional HAVE_STD_CXX11 is provided that is used in this
patch to enable the test in st/mesa if C++11 support is available.

50906e4583 broadcom/vc5: Do 16-bit unpacking of integer texture returns properly.
We were doing f16 unpacks, which trashed "1" values.  Fixes many piglit
texwrap GL_EXT_texture_integer cases.

80da60947b broadcom/vc5: Fix pausing of transform feedback.
Gallium disables it by removing the streamout buffers, not by binding a
program that doesn't have TF outputs.  Fixes piglit
"ext_transform_feedback2/counting with pause"

dfff9ce45e broadcom/vc5: Fix scheduling for a non-SFU R4 write after a dead R4 write.
The v3d_qpu_writes_r*() were only checking for fixed-function accumulator
writes, not normal ALU writes to those regs.

Fixes fs-discard-exit-2 on simulation (but not HW).

9ccb6621be broadcom/vc5: Add partial transform feedback query support.
We have to compute the queries in software, so we're counting the
primitives by hand.  We still need to make sure to not increment the
PRIMITIVES_EMITTED if we overflowed, but leave that for later.
