So the m68k port has failed to bootstrap since the introduction of
late-combine. My suspicion has been this is a backend problem. Sure
enough after bisecting things down (thank goodness for the debug
counter!) I'm happy to report m68k will bootstrap, though it's failing
the comparison check.
Similar to what we've seen elsewhere. The change to c++17 by default is causing
m68k to not bootstrap due to use of the "register" keyword. This patch removes
the half-dozen or so instances I immediately saw. I'll spin up another m68k
bootstrap attempt today/tonight.
