9dd6fee485 Recommit 211309 (StringMap::insert), reverted in 211328 due to issues with private, but non-deleted, move members. 
Certain versions of GCC (~4.7) couldn't handle the SFINAE on access
control, but with "= delete" (hidden behind a macro for portability)
this issue is worked around/addressed.

too).

47b284ce35 [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.

4ef09de13e 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.

03ef449917 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.

a23650bc01 give StringMap a new ctor which allows you to initialize it 
with an existing allocator.  The interesting use case of this
is that it allows "StringMap<whatever, BumpPtrAllocator&>" for
when you want to allocate out of a preexisting bump pointer
allocator owned by someone else.
