Add Conversion to lower loop::ForOp to spirv::LoopOp.

loop::ForOp can be lowered to the structured control flow represented
by spirv::LoopOp by making the continue block of the spirv::LoopOp the
loop latch and the merge block the exit block. The resulting
spirv::LoopOp has a single back edge from the continue to header
block, and a single exit from header to merge.
