Be more robust on "extreme" (large absolute value)
arguments.  Originally reported by Daniel Connelly
as a problem with asinh() on large negative arguments,
asinh() used to bail out because an argument to log()
ended up being zero.  Ilya Zakharevich proposed using
Taylor's series in such cases, which for such large
arguments is a very good approximation.
