Log message:
	inline 64bit shifts by a constant (and shifts of 64bit constant by constant)
	(and optimize away shift/rotate of constant 0)
	some of this seems backwards, and is commented as such, but the
	test case and disassembly show it to be correct, need
	to study that more
	still to handle 64bit rotate by constant..
