better a_sc inline asm constraint on aarch64 and arm
"Q" input constraint was used for the written object, instead of "=Q"
output constraint.  this should not cause problems because "memory"
is on the clobber list, but "=Q" better documents the intent and more
consistent with the actual asm code.

this changes the generated code, because different registers are used,
but other than the register names nothing should change.
