safeOp.pow

Raise base to the exp power.

Errors that may be signalled if neither input is floating-point:

IntFlag.posOver or IntFlag.negOver if the absolute value of the result is too large to represent with the return type.
exp < 0, IntFlag.undef is raised because std.math.pow would trigger an FPE given the same input.
