Increase the size of the stack reserved area.

This increases the size of the "reserved" area, used for handling stack
overflows, from 512 to 768 bytes.  There will be a corresponding
reduction in the amount of stack space available to interpreted threads
(which currently default to 12KB).

It turns out 512 bytes isn't quite enough space when class lookup throws
an exception while resolving "catch" block classes during a stack
overflow error.

For bug 2398031.
