configure.ac: supersede --enable-gallium-llvm over --enable-llvm

Currently we have extra (somewhat questionable) modularity, such that
one could build some parts with LLVM while others w/o.

That is extremely fragile, error prone and requires quite noticable

nv50/ir: always return 0 when trying to read thread id along unit dim

Many many many compute shaders only define a 1- or 2-dimensional block,
but then continue to use system values that take the full 3d into
account (like gl_LocalInvocationIndex, etc). So for the special case
that a dimension is exactly 1, we know that the thread id along that
axis will always be 0, so return it as such and allow constant folding
to fix things up.

nvc0/ir: fix robustness guarantees for constbuf loads on kepler+ compute

Kepler and up unfortunately only support up to 8 constbufs. We work
around this by loading from constbufs as if they were storage buffers.
However we were not consistently applying limits to loads from these
buffers. Make sure to do the same thing we do for storage buffers.

Apparently GL 4.5 requires 14 of these (there's a "*" in the spec, but
