JDK-8188764 - Obsolete AssumeMP and then remove all support for non-MP builds
Description
JDK-8188764 removed many uses of `os::is_MP`, effectively defaulting it to `true`, but some Shenandoah code still has it. This is a simple omission. All current uses on x86 already imply lock prefix, so this is a cleanup, and not a functional change.
Comments
Fix Request (17u) Clean backport to keep codebases in sync and avoid surprises when os::is_MP is misbehaving.
