8268389: [lworld] Tests must be update after core reflection changes for the L/Q model

[fparain]

Fix all but one test to pass with the new L/Q model and the new core reflection.
The failing test, TestIntrinsics.java might be a real VM bug and not a test bug, but it is C2 related.

should the first MyValue1.class.asValueType() in line 75 be MyValue1.class (to match MyValue1.ref.class) ?

[fparain]

MyValue1.class.asValueType() and MyValue1.class are different (secondary mirror vs primary mirror), so changing from MyValue1.class.asValueType() to MyValue1.class would make this line to fail.
However, this line has not been fixed properly (it accidentally duplicates line 74).
Now, I think the right way to fix it is:

Asserts.assertFalse(test1(MyValue1.class, MyValue.class.asValueType()), "test1_4 failed");

The test has to be inverted from assertTrue to assertFalse to verify that the two mirrors are distinct.

[mlchung]

In fact MyValue1.class == ldc QMyValue1; and MyValue1.class and MyValue1.class.asValueType() are the secondary mirror. MyValue1.ref.class is the primary mirror.

AFAIU, these tests fail in -Xcomp mode (pass in -Xint mode) as it's awaiting for the JIT phase 2 support (JDK-8267932) which is blocked by the core reflection support.

Would disabling -Xcomp run from these tests be a better temporay fix until JDK-8267932?

[hseigel]

The changes look good!
Thanks, Harold

In fact `MyValue1.class` == `ldc QMyValue1;` and `MyValue1.class` and `MyValue1.class.asValueType()` are the secondary mirror. `MyValue1.ref.class` is the primary mirror.

Mandy,

Thank you for the clarification. Many of the changes are in fact incorrect(invalid changes from x.ref.class to x.class).
I was confused because getClass() always returns the primary mirror and .class returns either the primary or the secondary (I should have known that because I reviewed your code implementing this).
I?ll back out this changeset and re-do it correctly.
