[PATCH] D50127: [Support] use larger character set for creating unique filenames

[Zachary Turner via llvm-commits]

It would be an extra line of code, but I think this would be clearer (with
even less chance of collision) if you just choose a random number in [0,35]
and map it to [0-9][a-z]. The bit twiddling and array indexing seems like
unnecessary cleverness and someone could accidentally come along and break
it if they weren’t careful.
