Fixes part of 8329
Context
The 3.5 version of
InternableStringuses a simpler hash code calculation, the results of which were not matching the 4.72/Core version. This manifested as a failing unit testRetainsLastStringWithGivenHashCodein VS.Changes Made
Made the routine return the same numbers as the other implementation. It fixed the UT and also made the hash code "better" as previously we were shifting instead of rotating bits.
Testing
Existing unit tests (previously failing).
Notes
It would be nice to figure out how to run 3.5 tests in CI.
