Jonas Paulsson 9222b91e24 [SelectionDAGBuilder] Chain prefetches less aggressively. ...

Prefetches used to always be chained between any previous and following
memory accesses. The problem with this was that later optimizations, such as
folding of a load into the user instruction, got disrupted.

This patch relaxes the chaining of prefetches in order to remedy this.
