RFR: 8261239: Upstream 8258238: Some jextract samples crash with: "updating map that does not need updating"

[Jorn Vernee]

Hi,

This patch upstreams a fix and the accompanying test from the panama-foreign repo, that fixes an assertion when walking the stack with a register map that does not need updating.

While updating the map any ways seems benign, the fix avoids running into the assertion in certain test configurations when running foreign-linker tests.

Testing: Tier 1-2

Thanks,
Jorn
