Summary Profile allocations and track allocation mode in libPAS

rdar://122419407 We already have hooks at the bmalloc/WTF level to profile allocations, and categorize these allocations via compactible (can be referenced by a compact pointer) and a variety of non-compactible (e.g. JSCell, non-JSCell, in-Gigacage, etc) discriminators. Up until now we haven't added much profiling to allocation sites in libPAS, where the bulk of the allocation logic occurs, but it seems useful to be able to not only measure the amount of times we fastMalloc something, but also whether it hits the fast or slow path of a libPAS local allocator, for example.
