Hi all,

Please review patch:

Problem:
JDK-8011044 removed support of javac 1.5  sources and target platform, 
but compiler/6932496/Test6932496.java uses it to generate jtr, ret 
instructions

Fix:
the test was rewritten by using ASM

jbs: https://bugs.openjdk.java.net/browse/JDK-8051484
testing:
  - locally
  - I'm not able to reproduce 6932496 on 1.7.0-b80 neither by the 
original version nor the new one, since  but I reproduced it on jdk9 w/o 
the fix for 8051484, src/share/vm/c1/c1_LIR.cpp:

> LIR_Opr LIR_OprFact::value_type(ValueType* type) {
...
>   case addressTag: // return LIR_OprFact::addressConst(type->as_AddressConstant()->value());
>   case intTag    : return LIR_OprFact::intConst(type->as_IntConstant()->value());

> LIR_Opr LIR_OprFact::dummy_value_type(ValueType* type) {
...
>     case addressTag://return LIR_OprFact::addressConst(0);
>     case intTag:    return LIR_OprFact::intConst(0);
