Enable (disable) generation of code using decrement and branch,
DBcond(D), instructions. This is enabled by default for the C4x. To be
on the safe side, this is disabled for the C3x, since the maximum
iteration count on the C3x is @math{2^23 + 1} (but who iterates loops more than
@math{2^23} times on the C3x?). Note that GCC will try to reverse a loop so
iteration count on the C3x is @math{2^{23} + 1} (but who iterates loops more than

that it can utilise the decrement and branch instruction, but will give
up if there is more than one memory reference in the loop. Thus a loop
where the loop counter is decremented can generate slightly more
