Jonas Paulsson 1b85e47f06 [LoopStrenghtReduce] Refactoring and addition of a new target cost function. ... Refactored so that a LSRUse owns its fixups, as oppsed to letting the LSRInstance own them. This makes it easier to rate formulas for LSRUses, since the fixups are available directly. The Offsets vector has been removed since it was no longer necessary. New target hook isFoldableMemAccessOffset(), which is used during formula rating. For SystemZ, this is useful to express that loads and stores with float or vector types with a big/negative offset should be avoided in loops. Without this, LSR will generate a lot of negative offsets that would require extra instructions for loading the address.
