teak-llvm/clang/test/OpenMP/schedule_codegen.cpp
Michael Kruse 0535137e4a [CodeGen] Generate llvm.loop.parallel_accesses instead of llvm.mem.parallel_loop_access metadata. 
Instead of generating llvm.mem.parallel_loop_access metadata, generate
llvm.access.group on instructions and llvm.loop.parallel_accesses on
loops. There is one access group per generated loop.

This is clang part of D52116/r349725.
