Request for review(S): 6986270: guarantee(*bcp != Bytecodes::_monitorenter || exec_mode != Deoptimization::Unpack_exception) fails

[Igor Veresov]

This guarantee should hold true for C2 but is not necessarily true for 
C1. The fix is to propagate the compiler type of the deopting method to 
vframeArrayElement::unpack_on_stack() and apply the guarantee only to 
c2-compiled methods.
