array: Check for integer overflow during allocation
This fixes #229, where creating a new array can cause array to allocate
a smaller array than it thinks it allocates due to integer overflow,
resulting in memory unsafety.
This breaks the rts/overflow1 test, which relied on this unchecked
overflow. I fix it by reimplementing the test in terms of newByteArray#
directly.
Updates the array submodule.
