Teach LoopUnrollPass to respect loop unrolling hints in metadata.

[This is resubmitting r210721, which was reverted due to suspected breakage
which turned out to be unrelated].

Some extra review comments were addressed. See D4090 and D4147 for more details.

The Clang change that produces this metadata was committed in r210667

Patch by Mark Heffernan.
