Request for reviews (S): 6823453: DeoptimizeALot causes fastdebug server jvm to fail with assert(false,"unscheduable graph")

[Vladimir Kozlov]

New (fourth?) version of the fix suggested by Tom.

I added the test case when array length is not defined
until loop optimizations. Only this version can compile it.
