Benny Halevy bb36237cf4 topology: optimize compare_endpoints ...

This function is called on the fast data path
from storage_proxy when sorting multiple endpoints
by proximity.

This change calculates numeric node diff metrics
based on each address proximity to a given node
(by <dc, rack, same node>) to eliminate logic
branches in the function and reduce its footprint.

based on objdump -d output, compare_endpoints
footprint was reduced by 58.5% (3632 / 8752 bytes)
with clang version 15.0.7 (Fedora 15.0.7-1.fc37)
