transform fmin/fmax calls when possible (PR24314) If we can ignore NaNs, fmin/fmax libcalls can become compare and select (this is what we turn std::min / std::max into). This IR should then be optimized in the backend to whatever is best for any given target. Eg, x86 can use minss/maxss instructions. This should solve PR24314: https://llvm.org/bugs/show_bug.cgi?id=24314 Differential Revision: http://reviews.llvm.org/D11866 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@245187 91177308-0d34-0410-b5e6-96231b3b80d8
