[11u] RFR: 8222072: JVMTI GenerateEvents() sends CompiledMethodLoad events to wrong jvmtiEnv

[Lindenmaier, Goetz]

Hi,

I would like to downport this fix for jvmti. 
Some of the coding added here is needed by follow-up 
8212160: JVMTI agent crashes with "assert(_value != 0LL) failed: resolving NULL _value"
which I downported for 11.0.10-oracle parity.

The change applies clean, but I had to convert the test coding 
from C++ to C.

Please review.
