[jdk11u-dev] RFR: 8279924: [PPC64, s390] implement frame::is_interpreted_frame_valid checks [v3]

[Martin Doerr]

> Backport of JDK-8279924. Applies cleanly except Copyright update. `is_in_stack_range_incl` needs to get replaced by 11u code like on other platforms (see 2nd commit). An old assertion is not compatible with this new code. I've integrated the removal backport from JDK-8254158 (see 3rd commit, x86 removed it already with JDK-8146546 in JDK9).

Martin Doerr has updated the pull request incrementally with one additional commit since the last revision:

  Integrate bad assert removal from JDK-8254158 (x86 was already changed by JDK-8146546).
