[PATCH] D45736: [SimplifyLibcalls] Replace locked IO with unlocked IO

[Dávid Bolvanský via Phabricator via llvm-commits]

Not sure about benchmarks, if there are any for C FILE IO. But in my tests and programs I see small improvements - yes, they read and writ a lot.

Would you like to remove it?
 ... or make it off by default and prove option to turn this on if anybody wants?
