> Able to get a 3-7% improvement on Perf -i by creating a specialized version
> of BinaryDecoder.readInt() that uses the same code as readLong() but uses
> ints instead of long for all its math and bit arithmetic.
> The performance improvement is larger on a 32-bit VM (around 7%) than on a
> 64-bit VM (around 3%).
