Instead of always lowering everything, we add a threshold such that if
the total indirected array size (AoA size) is above that threshold, it
won't lower. It's assumed that the driver will sort things out somehow
by, for instance, lowering to scratch.

The OpenCL image_width/height/depth functions have variants which can
take an LOD parameter. More importantly, LLVM-SPIRV-Translator always
generates OpImageQuerySizeLod even if the LOD is guaranteed to be zero.
Given that over half the hardware out there has an LOD field for image
size queries (based on a rudimentary scan through their NIR -> whatever
code), we may as well just add the source to the NIR intrinsic. If this
is ever a problem for anyone, the lowering is pretty trivial.
I've also added asserts to everyone's drivers that should alert them if
they ever see an LOD other than zero. This will never happen with GL or
Vulkan so there's no need for panic.

Having a single init function works as expected for shared llvm, but
when using a static llvm only one llvm will get initialized.
This commit introduces 2 separate init function:
- shared llvm = single public init function
