RAGreedy is better about hinting now. Or maybe we are just getting lucky. llvm-svn: 144473

Fix memcpy lowering when addresses are 4-byte aligned but size is not multiple of 4. llvm-svn: 43234

Recommit r129383. PreRA scheduler heuristic fixes: VRegCycle, TokenFactor latency. Additional fixes: Do something reasonable for subtargets with generic itineraries by handle node latency the same as for an empty itinerary. Now nodes default to unit latency unless an itinerary explicitly specifies a zero cycle stage or it is a TokenFactor chain. Original fixes: UnitsSharePred was a source of randomness in the scheduler: node priority depended on the queue data structure. I rewrote the recent VRegCycle heuristics to completely replace the old heuristic without any randomness. To make the ndoe latency adjustments work, I also needed to do something a little more reasonable with TokenFactor. I gave it zero latency to its consumers and always schedule it as low as possible. llvm-svn: 129421

rip out a ton of intrinsic modernization logic from AutoUpgrade.cpp, which is for pre-2.9 bitcode files. We keep x86 unaligned loads, movnt, crc32, and the target indep prefetch change. As usual, updating the testsuite is a PITA. llvm-svn: 133337
