d554380850 * Support pointer indexing 
* Unsized arrays are a thing of the past, remove DoInsertArrayCast family
* Remove cases were we would get into infinite loops because we would insert a cast
  which would then be removed, inserting a different cast, ad infinitum...
* Remove some code that should be redundant with ExprTypeConvert code

97ac4ee02e Many many changes and bugfixes: 
* Remove support for unsized arrays
* Add pointer indexing support
* Allow more arbitrary malloc type changes (which are too generous currently
  and should be fixed in the future)
* Allow more and better conversions

29c147302f * Refactor trace values to work as a proper pass. Before it used to add 
methods while the pass was running which was a no no.  Now it adds the
  printf method at pass initialization
* Revamp code to use printf calls instead of the old style print_<type>
  calls.
* Simplify code
