32bit code generation and llvm >= 2.7 used a different optimization pass
order - this code was initially introduced (2010-07-23) by
815e79e72c, apparently due to buggy code being
generated with then brand new llvm versions (which was llvm 2.7 plus pre 2.8
devel).
It seems very highly likely that whatever this bug was it has been fixed in
newer llvm versions, though there's no easy way to test this - the mentioned
piglit test has been removed years ago, and even if you'd build it I'm
sceptical the glsl compiler would still produce the required code to trigger
it.
I have no idea what a good order of passes is, but just remove the workaround
and use the same order everywhere.

It makes more sense to link the core and common parts of the driver as the
target is build. Additionally this will help us drop duplicating symbols
for targets that static link mulitple pipe-drivers. Only egl-static needs
that currently with more to come.

The loops for updating the multiple packed fields in SP_VS_OUT[] and
SP_VS_VPC_DST[] will zero out one register beyond the last that on

when looking at cmdstream dumps) unless we have maximum (16) varyings.

We need to size input/output tables big enough for special inputs/

count towards the hw limit of 16 attributes or 16 varyings, we do
still need to track them all the same.

All shaders had the same name.
We could probably use some identifier per shader too, but for now only use
the variant number.
Reviewed-by: Jose Fonseca <jfonseca@vmware.com>
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.

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).

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.
