re PR target/85683 (GCC 8 stopped using RMW (Read Modify Write) instructions on x86[_64])
PR target/85683
* config/i386/i386.md: Add peepholes for mem {+,-,&,|,^}= x; mem != 0
after cmpelim optimization.
* gcc.target/i386/pr49095.c: Add -masm=att to dg-options. Add
scan-assembler-times checking that except for [fh]*xor other functions
don't use any load instructions.
