Notes on gd_regular.c

• In the Datrix model, statments which are expressions, labels, or declarations are represnted by just the expressions, labels, or objects themselves, as arcsons of the scope the statements are in.
• But in gcc, such statements are represented separately from their contents
• This transform excises the statement nodes, everywhere in the graph, in favour of the contents.
• Therefore this transform must follow the one (Block) which makes the arcson edges from the scope!
