Hi!
During testing with older gas I've noticed failures, where 0xf2 was a pasto
instead of the right 0xf3 for xrelease insn.
Fixed thusly, regtested on x86_64-linux and i686-linux, ok for trunk?
BTW, I wonder if dg-options shouldn't select -march=i686 for !lp64,
if somebody configures gcc to default to -march=i386, I guess xadd etc.
won't be emitted there.

* gcc.target/i386/hle-xadd-rel-1.c: Match .byte 0xf3 instead of
.byte 0xf2.
* gcc.target/i386/hle-sub-rel-1.c: Likewise.
* gcc.target/i386/hle-xchg-rel-1.c: Likewise.
* gcc.target/i386/hle-add-rel-1.c: Likewise.
