[PATCH] D70365: intrinsics attribute opt-out list proposal.

> One way to avoid some of the complexity would be to opt-out of everything with a single bit. So if this is set, you don't get any default attributes. Otherwise you get all.

Probably depends on what the initial list looks like.  I guess something like "nosync, norecurse, nounwind, willreturn" is reasonable for most intrinsics.  Given that list, probably an intrinsic that wants to opt-out of one of those will want to opt-out of all of them.

On a related note, we might want to consider doing something for pointer/memory handling as well, since that's currently pretty awkward. Most pointer arguments should be nocapture/nofree, but we don't really mark that consistently.
