The 'collapse' clause on a 'loop' construct is used to specify how many nested loops are associated with the 'loop' construct. It takes an optional 'force' tag, and an integer constant expression as arguments. There are many other restrictions based on the contents of the loop/etc, but those are implemented in followup patches, for now, this patch just adds the AST node and does basic argument checking on the loop-count.
