C2 inlining policy is too strict when it comes to inlining DMH linkers. The compiler performs access checks on target method and sometimes it breaks inlining. Such checks can be skipped since MemberNames are checked during construction.

The fix is to disable access checks when inlining DMH linkers.

Testing: regression test, java/lang/invoke tests, nashorn, octane.

Best regards, Vladimir Ivanov
