RFR: 8332827: [REDO] C2: crash in compiled code because of dependency on removed range check CastIIs [v2]

[Roland Westrelin]

> The failures that caused the backout were due to a bug in:
> 
> `find_or_make_integer_cast()`
> 
> which caused the `_range_check_dependency` field's value of the
> existing cast node to not be set in the new cast node. I re-ran some
> testing with this fixed and current jdk repo and found that a few
> vectorization tests fail now because the patch pushes range check
> `CastII` nodes through `AddI`/`SubI`. To fix this, I delayed that
> transformation to after loop opts.
