This patchset LGTM. On my machine there doesn't seem to be any
measurable performance change for the numeric regression test,
but numeric_big gets about 15% faster.
The only additional thought I have, based on your com

I took a quick look through thes
Attached are 3 small patches that improve the performance of numeric
division. Patch 0002 seems to have the biggest impact, but I think
they're all worth including, since they're quite simple changes, with
noticeable performance gains.
Patch 0001 vectorises the inner loop of div_var_fast(). This
