  [LVI] Drop bitcast handling (NFCI)

The code only works on integer casts, and the only bitcasts
involving integers are trivial. The code as previously written
would try to handle things like float to integer bitcasts by
fetching a ConstantRange of a float value, which is an ill-defined
operation.
