This patch is part of the work to make PPCLoopDataPrefetch target-independent (http://thread.gmane.org/gmane.comp.compilers.llvm.devel/92758). Obviously the pass still only used from PPC at this point. Subsequent patches will start driving this from ARM64 as well. Due to the previous patch most lines should show up as moved lines. llvm-svn: 261265
