The original PR (#26123) had incorrect usage of SafeFetch32. This PR replaces that with the use of os::is_readable_range as proposed by @tstuefe (thank you!). In addition I found that code was no longer getting exercised by the regression test so I added a gtest for that (during which it was discovered that the new implementation in verify requires any gtest that uses it to be TEST_VM rather than TEST).

Testing: tiers 1-4

Thanks
