This simplifies a bunch of places that no longer need special treatment
of value_count == 1. We rely on LLVM to optimize away the 1-element vector
types.
This fixes a bunch of bugs where 1-element arrays are indexed indirectly.

The renumbering code didn't take into account that multiple VS exports
can have the same PARAM index. This also significantly simplifies
the renumbering. Thankfully, we have piglits for this:
spec@arb_gpu_shader5@arb_gpu_shader5-interpolateatcentroid-packing
spec@glsl-1.50@execution@interface-blocks-complex-vs-fs

LLVM 3.8:
- had broken indirect resource indexing
- didn't have scratch coalescing
- was the last user of problematic v16i8
- only supported OpenGL 4.1
This leaves us with LLVM 3.9 and LLVM 4.0 support for Mesa 17.2.

This assert wasn't in the original radeonsi code but I added
it without totally understanding the original code, it caused
some regressions in variable-indexing tessellation shaders.

This code can be shared by radv, we bump the max to
VARYING_SLOT_MAX here, but that shouldn't have too
much fallout.

Call site attributes are used since LLVM 4.0.
This also reverts commit b19caecbd6
"radeon/ac: fix intrinsic version check", because this is the correct fix.

They can vary at call sites if the intrinsic is NOT a legacy SI intrinsic.
We need this to force readnone or inaccessiblememonly on some amdgcn
intrinsics.
This is only used with LLVM 4.0 and later. Intrinsics only used with
LLVM <= 3.9 don't need the LEGACY flag.
gallivm and ac code is in the same patch, because splitting would be
more complicated with all the LEGACY uses all over the place.
