RFR: 8321141: VM build issue on MacOS after JDK-8267532

Thu Nov 30 23:34:12 UTC 2023

[JDK-8267532](https://bugs.openjdk.org/browse/JDK-8267532) added new method `ciMethodData::exception_handler_bci_to_data()` which has `ShouldNotReachHere()` call on one exit without returning any value.

Unfortunately `ATTRIBUTE_NORETURN` attribute  in `ShouldNotReachHere()` seems don't work with older versions of Xcode.

The fix is to add `return` statement.

Tested with old Xcode (12.4) I have. Also tested with tier1 which includes builds.
