[SCEV] Cap the number of instructions scanned when infering flags

This addresses a comment from review on D109845.  The concern was raised that an unbounded scan would be expensive.  Long term plan is to cache this search - likely reusing the existing mechanism for loop side effects - but let's be simple and conservative for now.
