Hi,

here's v2 of the set to do NOPs optimizations on a temporary buffer
after the last-minute conflict and resulting breakage before the last
merge window which made me retract those.

This v2 has been extensively tested on 6.9-rc1.

Thx.

v0:

here's a small set which sprang out from my reacting to the fact that
NOPs optimization in the alternatives code needs to happen on
a temporary buffer like the other alternative operations - not in-place
and cause all kinds of fun.

The result is this, which makes the alternatives code simpler and it is
a net win, size-wise:
