  [SPIR-V] Move structurizer to ISel prepare (#157886)

Some passes like LoopSimplify/SimplifyCFF are running between IRPasses
and ISelPrepare. This is an issue because the structurizer generates
OpSelectionMerge/OpLoopMerge instructions at specific places, and those
passes are moving them.
Moving the structurizer later solves this issue.
