Sanjay Patel 319a335961 [DAGCombine] (float)((int) f) --> ftrunc (PR36617)
fptosi / fptoui round towards zero, and that's the same behavior as ISD::FTRUNC, 
so replace a pair of casts with the equivalent node. We don't have to account for 
special cases (NaN, INF) because out-of-range casts are undefined.
