This results in slightly less code, but code that is much more readable.
It has the advantage of putting everything together in one place, all of
the code is self documenting, help messages are auto-generated, choices
are automatically enforced, and the syntax is much less C like, taking
advantage of python features and idioms.

Some shaders in Civilization V and Beyond Earth do
pow(pow(x, 2.2), 0.454545)
which is converting to and from sRGB colorspace.
A more general rule that replaces pow(pow(a, b), c) with pow(a, b * c)
actually regresses two shaders in Sun Temple in which the result of the
inner pow is used twice, once by another pow and once by another
instruction. Also, since 2.2 * 0.454545 isn't exactly one, the more
general pattern would have still left us with a pow, and I'm 2.2 *
0.454545 percent sure that's not what they want.
instructions in affected programs: 934 -> 886 (-5.14%)

A sequence number is written for 32-bits queries to make sure they are
ready, but not for 64-bits queries. Instead, we have to use a fence in
order to fix the HUD because it doesn't wait until the result is ready.

Previously, we just blasted out whatever VB's we had marked as "dirty"
regardless of which ones were used by the pipeline. Given that the stride
of the VB is embedded in the pipeline this can cause problems. One problem
is if the pipeline doesn't use the given VB binding we emit a bogus stride.
Another problem is that we weren't properly resetting the dirty bits when
the pipeline changed.
Previously, we waited until later and did a pass through the used surfaces
and did the relocations then. This lead to doing double-relocations which
was causing us to get bogus surface offsets.
We now have is_array() and without_array() that make the
code much clearer and remove the need for this.
For all remaining calls to this we already knew that
the type was an array so returning a null wasn't adding any value.
v2: use without_array() in _mesa_ast_array_index_to_hir() and don't use
without_array() in lower_clip_distance_visitor() as we want to make sure the
array is 2D.

Since the binding table pointer is only 16 bits, we can only have 64kb
of binding table state allocated at any given time. With a block size of
1kb, that amounts to just 64 command buffers, which is not enough.
get_immediate will return a const reference, the requested immediate
isn't necessarily in the x slot. Make sure to use the swizzle.

This commit adds support for the LunarG GLSL back-door as well as detecting
regular GLSL and SPIR-V. The SPIR-V path doesn't exist yet, so that will
cause an assert-fail.
Passing -module to glibtool causes the resulting library to be called
libSomething.so rather than libSomething.dylib on darwin.
Regardless if libOSMesa is a library or a module, it has been used as
the former for quite some time. Update the build to reflect that and
resolve the naming issue.

Previously, we used intrinsic->const_index[1] to represent "the number of
array elements to load" for load/store intrinsics. However, this set to 1
by every pass that ever creates a load/store intrinsic. Also, while it
might make some sense for registers, it makes no sense whatsoever in SSA.
On top of that, the i965 backend was the only backend to ever support it;
freedreno and vc4 just assert that it's always 1. Let's just delete it.

From ARB_program_interface_query:
"Note that if an interface enumerates a single active resource list
entry for an array variable (e.g., "a[0]"), a <name> identifying
any array element other than the first (e.g., "a[1]") is not
considered to match."
It doesn't apply to arrays of interface blocks but just to array
variables.

This was an oversight when GLSL1.30 was enabled, I think my

This fixes a bunch of tex-miplevel-selection tests under softpipe,
