[PATCH] D52117: Generate llvm.loop.parallel_accesses instead of llvm.mem.parallel_loop_access metadata.

Meinersbur added a dependency: D52116: Introduce llvm.loop.parallel_accesses and llvm.access.group metadata..

Instead of generating llvm.mem.parallel_loop_access metadata, generate llvm.access.group on instructions and llvm.loop.parallel_accesses on loops. Minimize the number of access groups by only creating one for loops that are parallel.
