instcombine: Migrate fprintf optimizations
This patch migrates the fprintf optimizations from the simplify-libcalls
pass into the instcombine library call simplifier.
Added:

- copied, changed from r168887, llvm/trunk/test/Transforms/SimplifyLibCalls/osx-names.ll
Removed:
llvm/trunk/test/Transforms/SimplifyLibCalls/FPrintF.ll
llvm/trunk/test/Transforms/SimplifyLibCalls/iprintf.ll
