Alexander Markov 1a1c7693d2 [VM/compiler] Fix range analysis for 64-bit fixed-size integers 
This CL corrects handling of overflows in range analysis to
account for wrap-around (which happens with new integer semantics).

* If there is an overflow while doing computations in range
  analysis, the resulting range is approximated as full int64 range.

* For symbolic range boundaries 'symbol + offset', offset is checked
  to stay within [kMinInt64 - kSmiMin, kMaxInt64 - kSmiMax] in order
  to guarantee that overflow doesn't occur.
