[PATCH] D43834: Fix use after free in PDB linker.

[Zachary Turner via Phabricator via llvm-commits]

Actually now I'm second guessing myself.  This fixes the case where we freed the `BumpPtrAllocator` used for discontiguous records, but when we close the `NativeSession` object, we also close the mapped view of the file.

I think a better fix is to simply keep a strong reference to the type server PDB's session until we're done.
