Nikita Popov 6fe1b695c4 [ConstantRange] Add isAllNegative() and isAllNonNegative() methods
Add isAllNegative() and isAllNonNegative() methods to ConstantRange,
which determine whether all values in the constant range are
negative/non-negative.

This is useful for replacing KnownBits isNegative() and isNonNegative()
calls when changing code to use constant ranges.
