[Inliner] Fix bugs for partial inlining with vectorusers/joshua/partial-inline

In the cost model of partial inlining, cost for intrinsics
will be applied. However, some intrinsics for vector have
invalid cost, which is not allowed for partial inlining.
Instead of assertion, we directly do not do partial
inlining in this circumstance to avoid compiling errors.
