Vlad, is it OK if I backport this patch to 4.4? I have tested it on 4.4 without
problems.

IRA does not create a conflict for p66 and p67 (in function triangle). One

So the only bug here is that -Os produces an extra move. That comes from the

Reload 0: reload_in (SI) = (reg:SI 1 dx [65])
GENERAL_REGS, RELOAD_FOR_INPUT
