7129284: +DoEscapeAnalysis regression w/ early build of 7u4 (HotSpot 23) on Linux

Removed code which tried to create edges from fields of destination objects of 
arraycopy to fields of source objects which could lead to significant time 
(minutes) spend in EA. Instead conservatively mark fields of source objects as
globally escape.

Also added 30 sec time limit for EA graph construction.

Verified with failed test (sje2010).

Thanks,
Vladimir
