The isScaledConstantInRange function takes upper and lower bounds which are checked after dividing by the scale, so the bounds checks for half, single and double precision should all be the same. Previously, we had wrong bounds checks for half precision, so selected an immediate the instructions can't actually represent. Differential revision: https://reviews.llvm.org/D58822 llvm-svn: 355305
