RFR: 8295413: com/sun/jdi/EATests.java fails with compiler flag -XX:+StressReflectiveCode

[Richard Reingruber]

With `StressReflectiveCode` C2 has inexact type information which can prevent ea
based optimizations (see `ConnectionGraph::add_call_node()`)

This pr changes the test jdk/com/sun/jdi/EATests.java to read the flag
`StressReflectiveCode`. If enabled it shall neither expect ea based optimizations
of allocations nor deoptimization of corresponding frames upon debugger access.

Tested on the standard platforms with fastdebug and release builds.


make test TEST=test/jdk/com/sun/jdi/EATests.java TEST_VM_OPTS="-XX:+IgnoreUnrecognizedVMOptions -XX:+StressReflectiveCode"
