RFR 8218995: Deprecate the -XX:FailOverToOldVerifier option

[Harold Seigel]

Hi,

Please review this change to deprecate the -XX:FailOverToOldVerifier 
option.  The following warning will be issued when the option is used:

    Java HotSpot(TM) 64-Bit Server VM warning: Option
    FailOverToOldVerifier was deprecated in version 13.0 and will likely
    be removed in a future release.

JBS Bug:  https://bugs.openjdk.java.net/browse/JDK-8218995

The fix was regression tested by running Mach5 tiers 1 and 2 tests and 
builds on Linux-x64, Windows, and Mac OS X, Mach5 tiers 3 -5 on 
Linux-x64, and by running JCK Lang and VM tests on Linux-x64.

Thanks, Harold
