This reduces ZoneEvent size from 32 to 30 bytes.

Memory usage reduction on selected traces (sizes in MB):

big             9902 -> 9527  (96%)
chicken         2172 -> 2107  (97%)
ctx-big          311 ->  309  (99%)
drl-l-b         1570 -> 1479  (94%)
long            5496 -> 5412  (98%)
mem             6468 -> 6468  (100%)
q3bsp-mt        5784 -> 5592  (96%)
selfprofile     1486 -> 1443  (97%)
