Ruby Memory Vector: Allow more than 4GB of memory
The memory size variable was a 32-bit int. This meant that the size of the
memory was limited to 4GB. This patch changes the type of the variable to
64-bit to support larger memory sizes. Thanks to Raghuraman Balasubramanian
for bringing this to notice.
