Fixing review comments - Using `APInt` for DeBruijn constant.

I am using `*DeBruijn.getRawData()` to get the integer from the APInt but it does not seem appropriate way. Can anyone suggest me good approach to fetch integer from an APInt? I went through `Constants.h` and found `getRawData()` is the only way to fetch a data pointer which then I have to derefer it.
