/* MIPS defines LOGICAL_OP_NON_SHORT_CIRCUIT to 0, so we split both
"a_elt || b_elt" and "b_elt && kill_elt" into two conditions each,
rather than using "(var1 != 0) op (var2 != 0)". Also, as on other targets,
we duplicate the header of the inner "while" loop. There are then
6 threading opportunities:
1x "!a_elt && b_elt" in the outer "while" loop
-> the start of the inner "while" loop,
skipping the known-true "b_elt" in the first condition.
1x "!b_elt" in the first condition
-> the outer "while" loop's continuation point,
skipping the known-false "b_elt" in the second condition.
2x "!kill_elt" in the inner "while" loop
-> the outer "while" loop's continuation point,
skipping the known-false "b_elt && kill_elt" in the second condition
2x "kill_elt->indx < b_elt->indx" in the first "while" loop
-> "kill_elt->indx == b_elt->indx" in the second condition,
skipping the known-true "b_elt && kill_elt" in the second
condition. */
