re PR target/85756 (wrong code at -Os on x86-64-linux-gnu in 32-bit mode)
PR target/85756
* config/i386/i386.md: Disallow non-commutative arithmetics in
last twpeephole for mem {+,-,&,|,^}= x; mem != 0 after cmpelim
optimization. Use COMMUTATIVE_ARITH_P test rather than != MINUS
in the peephole2 before it.
testsuite/ChangeLog:
* gcc.c-torture/execute/pr85756.c: New test.
