tp = TMP_ALLOC_LIMBS (2*n);
xp = tp + n;
does not add any between T and X (intended to hold n limbs each). So if
one doesn't use TMP_ALLOC_LIMBS_2, one should instead write
tp = TMP_ALLOC_LIMBS (n);
xp = TMP_ALLOC_LIMBS (n);
to get red zones for this common case. Right?
Maybe this is more overhead, in the non-debug case, than using
TMP_ALLOC_LIMBS_2. I'm not sure.
