      AArch64 call instructions only have a 26-bit range, so if the code cache is greater than 128 megabytes (and it is by default) compilations fail with out-of-range branches.

      C1 and C2 solved this by generating trampolines for Java calls. The Aarch64 JVMCI CodeInstaller doesn't generate trampolines, and we should fix it so that it does.
