RegisterCoalescer: Enable terminal rule by default
This appears to be forgotten switch flip from 2015. This seems to do a nicer job with subregister copies. Most of the test changes are improvements or neutral, not that many are light regressions. The worst AMDGPU regressions are for true16 in the atomic tests, but I think that's due to existing true16 issues. I also had to hack many hexagon tests to disable the rule. I have no idea how to update these tests. They appear to be testing specific scheduling and packet formation of later machine passes, so any change in the incoming mir is likely hiding whatever was originally intended. I'll open an issue to fixup these tests once this lands.
