Improve isTriviallyReMaterializable() documentation.

This should make it clear under which narrow circumstances implicit
physreg uses are okay when rematerializing and prevent people from
accidentally allowing too much when overriding
isReallyTriviallyReMaterializable() even with the weaker assert in the
RegisterCoalescer.
