Customer Impact
There was a bug where we would not mark a region as non-interruptible because it created references in registers that were not reported to GC. As such, if the GC kicks in, it will sporadically move non-GC pointers leading to crash or wrong behavior of the program.
Testing
Existing test coverage.
Risk
The bug was introduced with one of the refactoring changes and this PR just puts back those changes that were missed out.
