[aarch64-port-dev ] RFR (XS) 8228746: Revert incorrect StubRoutines::contains change

[Aleksey Shipilev]

Bug:
  https://bugs.openjdk.java.net/browse/JDK-8228746

Bad merge, very old, such shame. All code paths I found affect logging (e.g. demangling in hs_errs)
only, which must be why it is not catastrophic.

Fix:
