Sanjay Patel add74ff5ff Return undef on FP <-> Int conversions that overflow (PR21330). ... The LLVM Lang Ref states for signed/unsigned int to float conversions: "If the value cannot fit in the floating point value, the results are undefined." And for FP to signed/unsigned int: "If the value cannot fit in ty2, the results are undefined." This matches the C definitions. The existing behavior pins to infinity or a max int value, but that may just lead to more confusion as seen in: http://llvm.org/bugs/show_bug.cgi?id=21130 Returning undef will hopefully lead to a less silent failure.
