matches the ``llvm.loop.parallel_accesses`` list.
If all memory-accessing instructions in a loop have
``llvm.loop.parallel_accesses`` metadata that refers to that loop, then the
``llvm.access.group`` metadata that each refer to one of the access
groups of a loop's ``llvm.loop.parallel_accesses`` metadata, then the
loop has no loop carried memory dependences and is considered to be a
parallel loop.
