Difference between [jdk20] Thread.ensureMaterializedForStackWalk and Blackhole.

[shami]

Hello,

I am trying to understand the JDK20 intrinsic -
Thread.ensureMaterializedForStackWalk (
https://github.com/openjdk/jdk/pull/10952/files).

It seems to be functionally equivalent to the *Blackhole.consume*
intrinsic.

Is there any subtle difference(s) between the two, or can one be
implemented using the other?

Thanks in advance.
Shami.
