No need for AcceleratorCache::takeOver...

...as it does the same as the copy assignment op.  And both of those are
apparently already only called with SolarMutex locked, so no need to lock it
again.  So the copy assignment op (as well as the other special memeber
functions) can be left implicitly-declared.  (And some uses of the original
takeOver can be optimized to use move assignment.)
