IrArrayLengthInstruction

Remarks

Takes a place rather than a value, and that is forced rather than chosen: an unsized array cannot be loaded, so there is no value to ask. Both targets agree — GLSL's data.length() and SPIR-V's OpArrayLength each name the block member, not a copy of it.

Only a buffer reaches here. A sized array answers with a constant in the binder, which is why this instruction is about the host's element count and nothing else.
