The representation in GIMPLE should also be discussed IMVHO. For
GIMPLE Alex has invented DEBUG_STMT, which has the same properties as
DEBUG_INSN in RTL (with one noteworthy difference, namely that having
note-like GIPMLE statements is a totally new concept while DEBUG_INSN
is just a wannabe-real-insn INSN_NOTE).
