this to a NOTE: because pari/gp results start to get rounded incorrectly
after 192 bits of precision. APInt and pari/gp never differ by more than
1, but APInt is more accurate because it does not lose precision after 192
bits as does pari/gp.

These will be used in upcoming patches to avoid virtual function call when
the client knows it is a ConstantInt.

common pattern with isNullValue, isAllOnesValue, etc. It also helps to
prevent things like getZExtValue() == 1, which could assert for large
bitwidths.

and back. While this is not strictly necessary, it does pave the way for
future changes in casting. It should now be possible to improve vector
casting to deal with un-equal fp/int sizes.
