[PATCH] D31094: [BuildLibCalls] emitPutChar should infer its function attributes

You could use a debug counter to limit instcombine to one pass over the function; see http://llvm.org/docs/ProgrammersManual.html#adding-debug-counters-to-aid-in-debugging-your-code .  Probably worth doing if you're planning to write more similar fixes.
