[jdk11u-dev] RFR: 8222926: Shenandoah build fails with --with-jvm-features=-compiler1

[Jie Fu]

Hi all,

As discussed here https://github.com/openjdk/jdk11u-dev/pull/921#issuecomment-1073341167 , I'd like to backport this patch to fix the build failure of jdk11u when c1 is disabled.

The patch doesn't apply cleanly since most of the changes are already in the jdk11u repo.
Actually, only two include statements are added in the backport, so the risk is low.

Thanks.
Best regards,
Jie
