sh: Fix sh4a llsc-based cmpxchg()
This fixes up a typo in the ll/sc based cmpxchg code which apparently
wasn't getting a lot of testing due to the swapped old/new pair. With
that fixed up, the ll/sc code also starts using it and provides its own
atomic_add_unless().

sh: Relax inline assembly constraints
When dereferencing the memory address contained in a register and
modifying the value at that memory address, the register should not be
listed in the inline asm outputs. The value at the memory address is an
output (which is taken care of with the "memory" clobber), not the register.
