Both explicit and implicit.
Using vtx 0 (as existing llvm code implies) does not work for dynamic offsets.

Hi,
I ran into problem when using VTX_READ from constant buffer would work only for
0 index. The LLVM code implied that it should work (or maybe they considered
constant offsets only), but I could not find one way or the other in ISA docs.
Switching to vtx#3 fixed the problem, though I'm not sure if it's the right
solution.
thanks,
Jan
