order to minimise memory losses due to alignment padding. Not yet enabled
by default at any optimization level, but can be (de)activated separately
via -Oo(no)orderfields
o added separate tdef.structalignment method that returns the alignment
of a type when it appears in a record/object/class (factors out
AIX-specific double alignment in structs)
o changed the handling of the offset of a delegate interface
implemented via a field, by taking the field offset on demand
rather than at declaration time (because the ordering optimization
causes the offsets of fields to be unknown until the entire
declaration has been parsed)
