e40fa529cd Dramatically simplify recursive type processing. Fixed a few bugs, a few still remain :( 
Why does this stuff have to come up NOW?

5ee08db6ce Support floating point numbers in expodential form so that small numbers don't get truncated, which broke the health benchmark

7682955ac0 * Add comments for peepholes 
* 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.  :)

8b30d77212 * Implement expression type conversion for constant values 
* 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
