9d51166419 [bigint] Make kMaxLength platform-independent. 
Taking kSystemPointerSize into account when determining the maximum
allowed BigInt size accidentally made the limit platform-specific.
This patch chooses a platform-independent constant (1<<30) instead.

62d1f78245 [bigint] Fix throwing in Exponentiate() 
When the multiplication steps fail, they have already thrown an
exception internally, so we should not throw another.
The power-of-two fast path erroneously did not throw at all for
a few input values.

b5997de8a9 [bigint] Fix accidental input modification in Divide 
"AbsoluteDivSmall" had a shortcut path for abs(divisor) == 1 where
it would simply return the dividend as result. However, its caller
"Divide" was blissfully ignorant of this trick and would therefore
simply set the value's sign as needed, modifying the input.
This CL prevents that, while continuing to avoid the full division
algorithm for abs(divisor) == 1.
