Something unidentified at the moment is causing the arrays benchmarks to
deopt when run with the TurboFan compiler. Refactor the test to use an
inner function that can be correctly optimized by TurboFan and

The fast base64 decoder used to switch to the slow one permanently when
it saw a whitespace or other garbage character. Since the most common
situation such characters may be encountered in is line-wrapped base64
data, a more profitable strategy is to decode a single 24-bit group with
the slow decoder and then continue running the fast algorithm.
