nir: Recognize open-coded bitfield_reverse.

Helps 11 shaders in UnrealEngine4 demos.

I seriously hope they would have given us bitfieldReverse() if we
exposed GL 4.0 (but we do expose ARB_gpu_shader5, so why not use that
anyway?).

instructions in affected programs: 4875 -> 4633 (-4.96%)
cycles in affected programs: 270516 -> 244516 (-9.61%)

I suspect there's a *lot* of room to improve nir_search/opt_algebraic's
handling of this. We'd actually like to match, e.g., step2 by matching
step1 once and then doing a pointer comparison for the second instance
of step1, but unfortunately we generate an enormous tuple for instead.

The .text size increases by 6.5% and the .data by 17.5%.

   text     data  bss    dec    hex  filename
  22957    45224    0  68181  10a55  nir_libnir_la-nir_opt_algebraic.o
  24461    53160    0  77621  12f35  nir_libnir_la-nir_opt_algebraic.o

I'd be happy to remove this if Unreal4 uses bitfieldReverse() if it is
in a GL 4.0 context once we expose GL 4.0.

nir: Handle large unsigned values in opt_algebraic.

The next patch adds an algebraic rule that uses the constant 0xff00ff00.

Without this change, the build fails with

   return hex(struct.unpack('I', struct.pack('i', self.value))[0])
   struct.error: 'i' format requires -2147483648 <= number <= 2147483647

The hex() function handles integers of any size, and assigning a
negative value to an unsigned does what we want in C. The pack/unpack is
unnecessary (and as we see, buggy).

nir: Do opt_algebraic in reverse order.

Walking the SSA definitions in order means that we consider the smallest
algebraic optimizations before larger optimizations. So if a smaller
rule is part of a larger rule, the smaller one will happen first,
preventing the larger one from happening.

GLsync objects had a race condition when used from multiple threads
(which is the main point of the extension, really); it could be
validated as a sync object at the beginning of the function, and then
deleted by another thread before use, causing crashes. Fix this by
changing all casts from GLsync to struct gl_sync_object to a new
function _mesa_get_and_ref_sync() that validates and increases
the refcount.

In a similar vein, validation itself uses _mesa_set_search(), which
requires synchronization -- it was called without a mutex held, causing
spurious error returns and other issues. Since _mesa_get_and_ref_sync()

radeonsi: re-order the perfcounter hardware blocks

As documented in the comment, AMD GPUPerfStudio unfortunately hardcodes the
order of performance counter groups. Let's do the pragmatic thing and present
the same order as Catalyst/Crimson.

radeonsi: Allow dumping LLVM IR before optimization passes

Note that in order to compile the resulting IR with llc, you will first

main: Use a derived value for the default sample count

Previously the framebuffer default sample count was taken directly
from the value given by the application. On the i965 driver on HSW if
the value wasn't one that is supported by the hardware it would hit an
assert when it tried to program the state for it. This patch fixes it
by adding a derived sample count to the state for the default
framebuffer. The driver can then quantize this to one of the valid
values in its UpdateState handler when the _NEW_BUFFERS state changes.
_mesa_geometric_samples is changed to use the new derived value.
