[APInt] Use trailing bit counting methods instead of population count method in isAllOnesValue, isMaxSigendValue, and isMinSignedValue. NFCI
The trailing bit methods will early out if they find a bit of the opposite while popcount must always look at all bits. I also assume that more CPUs implement trailing bit counting with native instructions than population count.
