[PATCH] D48240: Try again to implement a FIFO task queue

[Zachary Turner via Phabricator via llvm-commits]

zturner added a comment.

This gets the `LLVM_ENABLE_THREADS=0` case working.  It does so by taking advantage of pointer invalidation properties of `std::deque`, so I can save off a pointer to the newly inserted element and just run tasks until the pointers match.
