This patch makes LSR generate better code for SystemZ in the cases of memory intrinsics, Load->Store pairs or comparison of immediate with memory. In order to achieve this, the following common code changes were made: * New TTI hook: LSRWithInstrQueries(), which defaults to false. Controls if LSR should do instruction-based addressing evaluations by calling isLegalAddressingMode() with the Instruction pointers. * In LoopStrengthReduce: handle address operands of memset, memmove and memcpy as address uses, and call isFoldableMemAccessOffset() for any LSRUse::Address, not just loads or stores. SystemZ changes: * isLSRCostLess() implemented with Insns first, and without ImmCost. * New function supportedAddressingMode() that is a helper for TTI methods looking at Instructions passed via pointers.
