Serge Pavlov f7c1a2152a Clean up empty struct/union recognition. 
Make use of getTypeSizeInChars to detect structs/unions of zero size. It allows
more accurate detection of types of zero size. It however has a side effect -
sequence of used types may change, that is why the test 'override-layout' was
modified.
