Which also implies that near term tweaks to avr's supported type sizes
for 4.0 are also unlikely, although could be supported for 4.1 if generally
desired.

(and somewhat related, upon reviewing things, 64-bit wide types may need to
be supported in only a constrained way, i.e. by possibly restricting one of
the source operands to memory, as supporting generalized three operand
register based 64-bit operations would otherwise seem to require too much
of the register file to be spilled to memory to likely be considered
productive; but haven't figured out how to best describe this reasonably in
rtl yet.)
