tree-optimization/100359 - restore unroll at -O3
This fixes a mistake done with r8-5008 when introducing
allow_peel to the unroll code. The intent was to allow
peeling that doesn't grow code but the result was that
with -O3 and UL_ALL this wasn't done. The following
instantiates the desired effect by adjusting ul to UL_NO_GROWTH
if peeling is not allowed.
