[PATCH] D51006: LTO: make tempfiles in LTO cache subject to pruning

Hmm, I was aware of those races, but it's a little surprising that they would be the cause of a significant number of files being left around (since the files exist with their temporary names for the duration that the LLVM backend is running). I could buy that the Windows filesystem is slow enough that the sum of the racy windows would make up a significant fraction of that time, though.
