git-compat-util: st_add4: work around gcc 4.2.x compiler crash
Although changes by 5b442c4 (tree-diff: catch integer overflow in
combine_diff_path allocation, 2016-02-19) are perfectly valid, they
unfortunately trigger an internal compiler error in gcc 4.2.x:
combine-diff.c: In function 'diff_tree_combined':
combine-diff.c:1391: internal compiler error: Segmentation fault: 11
Experimentation reveals that changing st_add4()'s argument evaluation
order is sufficient to sidestep this problem.
Although st_add3() does not trigger the compiler bug, for style
consistency, change its argument evaluation order to match.
