Michael Anthony Knyszek 76bce1dd52 runtime: implement addrRanges.findSucc with a binary search 
This change modifies addrRanges.findSucc to more efficiently find the
successor range in an addrRanges by using a binary search to narrow down
large addrRanges and iterate over no more than 8 addrRanges.

This change makes the runtime more robust against systems that may
aggressively randomize the address space mappings it gives the runtime
(e.g. Fuchsia).

For #40191.
