cleanup write to argument array hack

The sparse interface is a kind of snaky that it change the input argument
array. The function sparse() does the same hack just to skip the files.

This patch add the ptr list for string. So sparse_initialize will
return list of file to compile. The string pointer is not aligned
at word boundary. This patch introduce non taged version of the ptr
list iteration function.
