gallivm: use llvm function calls for texturing instead of inlining

There are issues with inlining everything, most notably llvm will use much
more memory (and be slower) when compiling. Ideally we'd probably use
functions for shader functions too but texture sampling usually is responsible
for quite some IR (it can easily reach 80% of total IR instructions) so this
seems like a good start.
This still generates a different function for all different combinations just
like before, however it is possible llvm is missing some optimization
opportunities - it is believed though such opportunities should be somewhat
rare, but at least for now it can still be switched off (at compile time only).
It should probably make compiled code also smaller because the same function
should be used for different variants in the same module (so for the
opaque/partial or linear/elts variants).
No piglit change (though it does indeed speed up unrealistic tests like
fp-indirections2 by a factor of 30 or so).
Has a small negative performance impact in openarena - I suspect this could
be fixed by running some IPO passes (despite the private linkage, llvm right
now does NO optimization at all wrt anything going past the call, even if
there's just one caller - so things like values stored before the call and then
always written by the function etc. will not be optimized away, nor will dead
arguments (which we mostly shouldn't have) be eliminated, always constant
arguments promoted etc.).

v2: use proper return values instead of pointer function arguments.
llvm supports aggregate return values, which do wonders here eliminating
unnecessary stack variables - everything in fact will be returned in registers
even without any IPO optimizations. It makes the code simpler too.
With this I could not measure a peformance impact in openarena any longer
(though since there's still no constant value propagation etc. into the tex
functions this does not mean it couldn't have a negative impact elsewhere).

v3: fix some minor issues suggested by Jose, and do disassembly (and the
profiling) without hacks.

The callbacks used for getting the dynamic texture/sampler state were using

that way it's impossible to generate separate functions for texture sampling,
as will be done in the next commit. Hence, pass this pointer through all
interfaces so it can be passed to a separate function (technically, it would
probably be possible to extract this pointer from the current function instead,

glsl: avoid calling base_alignment when samplers are involved

Earlier commit 53bf7c8fd2e changed the logic to always call
base_alignment on structs. 1ec715ce8b12 hacked the function to return 0
for sampler fields, but didn't handle sampler arrays. Instead of
extending the hack, avoid calling base_alignment in the first place on
non-UBO uniforms.

plugin which uses OpenGL, this ends badly - with a dangling
pointer.
