The i965 backends pass something out of 'screen', which is allocated
per-process, making using this as a ralloc context not thread-safe.
All callers ra_alloc_interference_graph() already ralloc_free() its
return value.

It was totally broken:
- p_atomic_dec_zero() was returning the negation of the expected value
- p_atomic_inc_return()/p_atomic_dec_return() was
post-incrementing/decrementing, hence returning the old value instead
of the new
- p_atomic_cmpxchg() was returning the new value on success, instead of
the old
It is clear this never used in the past. I wonder if it wouldn't be better to
yank it altogether.

It was much easier for me to verify things build and run as expected
with this simple test, than building and testing whole Mesa.
With scons the test can be build and run merely by doing:
scons u_atomic_test
Building the test with autotools is left as a future exercise.

like how C11's stdatomic.h provides generic functions. GCC's __sync_*
builtins already take a variety of types, so that's simple.
MSVC and Sun Studio don't, but we can implement it with something that
looks a little crazy but is actually quite readable.
Thanks to Jose for some MSVC fixes!

GCC >= 4.1 support the __sync_* intrinsics. That seems like a
sufficiently old baseline.

There was already an intrinsics path that implemented all of the same

This shouldn't be a functional change since reg_belongs_to_class is just a
wrapper around BITSET_TEST. It just makes the code a little easier to

Presumbly this will let clang and other compilers use the built-ins as
well.
Notice two changes specifically:
- in _mesa_next_pow_two_64(), always use __builtin_clzll and add a
static assertion that this is safe.
- in macros.h, remove the clang-specific definition since it should
be able to detect __builtin_unreachable in configure.

The r300 gallium driver is using it outside of the Mesa tree, and I wanted
to do so for vc4 as well. Rather than make the multiple-definitions
problem even more complicated, just move it to more-shared code.

This gathers macros that have been included across components into util so
that the include chain can be more vertical. In particular, this makes
util stand on its own without any dependence whatsoever on the rest of

This hash table is used in core Mesa, the GLSL compiler, and the i965
driver, which makes it a good candidate for the new src/util module.
It's much faster than program/hash_table.[ch] (see commit 6991c2922f5
for data), and José's u_hash_table.c has a comment saying Gallium should
probably consider switching to a linear probing hash table at some point.
So this seems like the best candidate for a shared data structure.

For a long time, we've wanted a place to put utility code which isn't
directly tied to Mesa or Gallium internals. This patch creates a new
src/util directory for exactly that purpose, and builds the contents as
libmesautil.la.
ralloc seemed like a good first candidate. These days, it's directly
used by mesa/main, i965, i915, and r300g, so keeping it in src/glsl
didn't make much sense.
