RFR: 8364198: NMT should have a better corruption message

[Johan Sjölen]

Hi,

When NMT detects a memory corruption it outputs "NMT corruption" and some helpful metadata. I'd like to change the prefix to "NMT has detected a memory corruption bug.". I want to do this because the old message sounds like it is NMT itself that has become corrupted, which is not what's happened. Instead, it should be clear that NMT has helped detect a bug stemming from somewhere else. This is meant to help avoid someone misunderstanding the message.
