We are starting to add integer support to the compiler, which does not
get exercised with glsl feature level 120 and without advertising
integer support. But doing so breaks too many things right now. So
for now use a debug flag to conditionally expose the functionality
while it is in development.

Adds a large sum of TGSI opcodes to the a3xx compiler.
For integer opcodes we have 28 opcodes added.
Adds 4 floating point compare opcodes
If GLSL 1.30 is enabled, this allows the GLSL 1.30 piglits to have a
completion amount of 432/641.

All shaders had the same name.
We could probably use some identifier per shader too, but for now only use
the variant number.

The setup shaders were composed of both a fs shader number and a variant
number. But since they aren't tied to a particular fragment shader, the
former was a fixed zero while the latter was also always zero because
it was never assigned. So, similar to what the fs code does, use a ever
increasing number to give it a more catchy name (unlike fragment shaders
though where this number is for each explicitly created shader, we just use
it for the implicitly created variants).
And while here, fix whitespace a bit.

Previously the code used the total number of ubos being declared in the
linked program (so the ubos of all shaders combined), use the number
from the particular shader instead.
This fixes an assertion failure with piglit arb_uniform_buffer_object-maxblocks
seen in llvmpipe since 8a9f5ecdb1 as it now emits
code for each declared buffer, not just the ones actually used.

In 1d35f77228 support for multiple constant
buffers was introduced. This meant we had another indirection, and we did
resolve the indirection for each constant buffer access. This looks very
reasonable since llvm can figure out if it's the same pointer, however it
turns out that this can cause llvm compilation time to go through the roof
and beyond (I've seen cases in excess of factor 100, e.g. from 50 ms to more
than 10 seconds (!)), with all the additional time spent in IR optimization
passes (and in the end all of it in DominatorTree::dominate()).
I've been unable to narrow it down a bit more (only some shaders seem affected,
seemingly without much correlation to overall shader complexity or constant
usage) but it is easily avoidable by doing the buffer lookups themeselves just
once (at constant buffer declaration time).

Previously, ir_unop_any was implemented via a dot-product call, which
uses floating point multiplication and addition. The multiplication was
completely pointless, and the addition can just as well be done with an
or. Since we know that the inputs are booleans, they must already be in
canonical 0/~0 format, and the final SNE can also be avoided.

Provide a JITMemoryManager derivative which puts all generated code into
one memory pool instead of creating a new one each time code is generated.
This saves significant memory per shader as the pool size is 512K and
a small shader occupies just several K.
This memory manager also defers freeing generated code until you tell
it to do so, making it possible to destroy the LLVM engine while keeping
the code, thus enabling future memory savings.

Many instructions implicitly update the accumulator on Gen < 6. The instruction
scheduling code just calls add_barrier_deps() for each accumulator access on
these platforms, but a large class of operations don't actually update the
accumulator -- mostly move and logical instructions. Teaching the scheduling
code about this would allow more flexibility to schedule instructions.
