This new pass adds some basic ingredients to a module on which future passes are likely to depend, such as boolean constants and some specfic integer and floating-point values. This is not a fuzzer pass in the true sense in that it does not employ randomization, but it makes sense to define it as a fuzzer pass since it is the first of a number of transformations passes that the fuzzer will run on a module.
