This is for an upcoming change to the threshold on Apple targets for using a constant pool for FP literals versus building them with integer moves. This file is based on literal_pools_float.ll. I tried to bolt on to the existing test, but it got messy as that file is already testing a matrix of combinations, so creating this new file instead.
