[IR] Rename a couple calls to ConstantInt::getNullValue to Constant::getNullValue...

There is no getNullValue in ConstantInt. Due to inheritance, it's
really Constant::getNullValue.

Most of the calls in tree that use ConstantInt::getNullValue do
know the type is an integer. These two calls allow pointers so
shouldn't use "ConstantInt".
