[PATCH] D34838: Prototype: Reduce llvm-profdata merge memory usage further

I should say this doesn't currently pass the llvm-profdata regression tests - in part because it totally breaks/ignores the error handling (as mentioned in the description, there's ongoing list discussion about how to handle/address that). But enough of a rough prototype to handle some review feedback like naming, etc, I think. I haven't done a byte-for-byte comparison, but it seems to do similar work to the ToT version in my (error-free) test case.
