Description
The old trampoline call is disabled by default after https://bugs.openjdk.org/browse/JDK-8332689.
And the new solution (load target address from stub and call) has been baked for quite some time.
This propose to remove the related logic for the old trampoline call so that the code will be cleaner
and easier to maintain.
