Presumably an empty path yields a length of 0, so this could probably be written
as:

if (!layoutObject())
  return 0;
return asPath().length();

Done.

Somewhat similar to above, I think this could be written more succinctly as:

FloatPoint point;
if (layoutObject())
  point = asPath().pointAtLength(length);
return ...;

Done.
