Log message:
	oops: fix the wierdo shift whose direction is based on sign
	as opposed to the explicit left and right shift that are
	optimized with a custom calling convention to the C compiler
	helper function
	while at it, length some names:
	do_shift_64 => do_custom_calling_convention_shift_64
	do_rotate_64 => do_rotate_or_shift_64 (actually was correct before
	but now has another use)
