[rs6000] Adjust vectorization cost for scalar COND_EXPR
We found that the vectorization cost modeling on scalar COND_EXPR is a bit off
on rs6000. One typical case is 548.exchange2_r, -Ofast -mcpu=power9 -mrecip
-fvect-cost-model=unlimited is better than -Ofast -mcpu=power9 -mrecip (the
default is -fvect-cost-model=dynamic) by 1.94%. Scalar COND_EXPR is expanded
into compare + branch or compare + isel normally, either of them should be
priced more than the simple FXU operation. This patch is to add additional
vectorization cost onto scalar COND_EXPR on top of builtin_vectorization_cost.
The idea to use additional cost value 2 instead of the others: 1) try various
possible value candidates from 1 to 5, 2 is the best measured on Power9. 2)
from latency view, compare takes 3 cycles and isel takes 2 on Power9, it's
2.5 times of simple FXU instruction which takes cost 1 in the current
modeling, it's close. 3) get fine SPEC2017 ratio on Power8 as well.

My change was valid for targets that have a vector/scalar shift/rotate optabs

Since it does not seem to be easy to find out which targets would support it,
