The "r" constraint means any integer registers. But %b1/%h1 requires
the "Q" constraint.  OK for trunk and 4.3?
"movb %h1,(%2)" also requires the "R" constraint since you can't
encode "mov %Xh, (%rXX)". OK for trunk and 4.3?
Thanks.

PR testsuite/39451 * gcc.dg/asm-b.c: Use "Q" constraint on %b1/%h1 and "R" constraint on (%2).

Please also change ";" between asm instructions to "\n\t".

The patch is OK for mainline and branch with this change.

Thanks,
Uros.
