[Allocator] Pass the size to the deallocation function. This, on some
...
allocation libraries, may allow more efficient allocation and
deallocation. It at least makes the interface implementable by the JIT
memory manager.
However, this highlights problematic overloading between the void* and
the T* deallocation functions. I'm looking into a better way to do this,
but as it happens, it comes up rarely in the codebase.

When destroying a StringMap, just iterate over the map and destroy the contained elements. Don't reset them back to 0 as their values aren't needed any more. This results in ~StringMap() being mostly empty for POD types in BumpPtrAllocators

The count() function for STL datatypes returns unsigned, even
...
where it's only bool-like 1/0 result like std::set.count().
Some of the LLVM ADT already return unsigned count(), while
others return bool count().
This patch modifies SmallPtrSet, SmallSet, SparseSet count()
to return unsigned instead of bool:
1 instead of true
0 instead of false
More ADT to follow.

Reset StringMap's NumTombstones on clears and rehashes.
...
StringMap was not properly updating NumTombstones after a clear or rehash.
This was not fatal until now because the table was growing faster than
NumTombstones could, but with the previous change of preventing infinite
growth of the table the invariant (NumItems + NumTombstones <= NumBuckets)
stopped being observed, causing infinite loops in certain situations.
