Improve safety of resizeStorageToAtLeast

This CL has two purposes. To make sure I understand what is going
on with resizeStorageToAtLeast, and to remove the RELEASE_ASSERT.
There is no reason to crash if the math goes out of bounds. If things
get too big we can just set fReserve to INT_MAX, and continue to run.
