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 6991c2922f
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.

Note this by itself is not enough to fix scons build -- it will fail
until you remove:
rm -rf build/*/glsl/builtin_compiler
because that node was a filei before, but it will be now a directory.
This also means that bisecting across this change will require wiping
the build directory..

Before, the GLSL parser was getting rebuilt every time that scons was

In i965 GEN6+ (and I suspect most other hardware), gl_ClipDistance
needs to be laid out as a pair of vec4's (the first containing clip
distances 0-3, and the second containing clip distances 4-7).
However, it is declared in GLSL as an array of 8 floats.
This lowering pass acts at the GLSL level, modifying the declaration
of gl_ClipDistance so that it is an array of vec4's rather than an
array of floats, and renaming it to gl_ClipDistanceMESA. In addition,
it modifies all accesses to the array so that they access the
appropiate component of one of the vec4's.
Since some hardware may not internally represent gl_ClipDistance as a
pair of vec4's, this lowering pass is optional. To enable it, set the
LowerClipDistance flag in gl_shader_compiler_options to true.

This should allow lower_if_to_cond_assign to work in the presence of
discards, fixing bug #31690 and likely #31983.
NOTE: This is a candidate for the 7.9 branch.
This should save on the overhead of tree-walking and provide a
convenient place to add more instruction lowering in the future.
