[SPARC] Adding deoptimization handler foreign call
LoadDataAddressOp emitting now absolute addresses. (May be improved in future)
Removing epilogue baseclass/block end marking interface from LeaveCurrentStackFrameOp and LeaveDeoptimizedStackFrameOp to conform with the assertion in com.oracle.graal.lir.LIR.verifyBlock
Implement LIRGenerator.emitDeoptimizationFetchUnrollInfoCall for SPARC
Removing my changes for JUnit reporting from testrunner.
