The maximal value of a half is 0x7bff, which is 65504 when converted to an integer. This patch teaches that to computeConstantRange to compute a constant range with the correct maximum value. https://alive2.llvm.org/ce/z/BV_Spb https://alive2.llvm.org/ce/z/Nwuqvb The maximum value for a float converted in the same way is 3.4e38, which requires 129bits of data. I have not added that here as integer types so larger are rare, compared to integers types larger than 17 bits require for half floats. The MVE tests change because instsimplify happens to be run as a part of the backend, where it doesn't tend to for other backends. Differential Revision: https://reviews.llvm.org/D112694
