nir/opcodes: Make ldexp take an explicitly 32-bit int
There is no sense in having the double version of ldexp take a 64-bit integer. Instead, let's just take a 32-bit int all the time. This also matches what GLSL does where both variants of ldexp take a regular integer for the exponent argument. Reviewed-by: Samuel Iglesias Gonsálvez <[email protected]>
