* 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

Convert backward conversion of expression trees into a new more powerful bidirectional approach.  Add transforms for more instructions.

* Implement new peephole:
     // Peephole optimize the following instructions:
     // %t1 = cast {<...>} * %StructPtr to <ty> *
     //
     // Into: %t2 = getelementptr {<...>} * %StructPtr, <0, 0, 0, ...>
     //       %t1 = cast <eltype> * %t1 to <ty> *

  This peephole eliminated 9 evil casts in the health benchmark, and
  completely turned the addList method around.  :)

* Fix a problem setting a name on a constant value that died because no symbol table was passed in
* Add some comments describing the passes
* Implement a new peephole:
     // Peephole optimize the following instructions:
     // %t = cast <T1>* %P to <T2> * ;; If T1 is losslessly convertable to T2
     // store <T2> %V, <T2>* %t
     //
     // Into:
     // %t = cast <T2> %V to <T1>
     // store <T1> %t2, <T1>* %P
