Various improvements to MemoryBuffer::getFile:
...
- Use a RAII object to close the FD.
- Use sys::StrError instead of thread-unsafe strerror calls.
- Recover gracefully if read returns zero. This works around an issue on
DragonFlyBSD where /dev/null has an st_size of 136 but we can't read 136 bytes
from it.

Introduce another Reset() method in BumpPtrAllocator that calls a destructor
...
on all objects it has allocated, if they are all of the same size and alignment.
Use this to destruct all VNInfos allocated in LiveIntervalAnalysis (PR6653).
valnos is not reliable for this purpose, as seen in r99400
(which still leaked, and sometimes caused double frees).

Add the ability to "intern" FoldingSetNodeID data into a

BumpPtrAllocator-allocated region to allow it to be stored in a more

FastFoldingSetNode to avoid leaking memory in the case where a
FoldingSetNodeID uses heap storage, and to reduce overall memory
usage.
