My concern is that we're creating needless differences between
aarch64/jdk8u and aarch64/jdk8u-shenandoah.

It will when we pull in whatever 8u version they are destined for.
8187577 is scheduled for the next
CPU (8u181), the other two for the feature update 8u192 in October.

Clearly though, you want them for Shenandoah earlier than that. In
this case, add them to aarch64/jdk8u
and then merge that into the Shenandoah tree, rather than applying
directly to Shenandoah. That way,
all three trees (the two aarch64 project ones and the Shenandoah
project one) have these fixes.
