Actually, for getHighBitsSet and getLowBitsSet, don't make a 0 bit size

illegal. Instead do the 0 valued construction for the user. This is because
the caller may not know (or care to check) that the number of bits set is
zero.

Make it illegal to set 0 bits in getHighBitsSet and getLowBitsSet. For that

they should have used the uint64_t constructor. This avoids causing
undefined results via shifts by the word size when the bit width is an
exact multiple of the word size.

In the getBitsSet function, don't optimize for a common case that is
...
already covered by getLowBitsSet (i.e. when loBits==0). Consequently, remove
the default value for loBits and reorder the arguments to the more natural
loBits, hiBits order. This makes it more clear that this function is for bit
groups in the middle of the bit width and not towards one end or the other.

Add a non-virtual test for zero, isZero, and rename isUnitValue isOne.
...
These will be used in upcoming patches to avoid virtual function call when
the client knows it is a ConstantInt.

Add an isUnitValue method for comparison against 1. This just follows a
...
common pattern with isNullValue, isAllOnesValue, etc. It also helps to
prevent things like getZExtValue() == 1, which could assert for large
bitwidths.
