bbca4bb7a6 Propagating constants to arguments can make other arguments constant. For now
do something dumb, and inefficient, but more complete.

4fb1540128 Get the list of PHI node values before the basic block is split. Also, add
PHI node entries for unwind instructions just like for call instructions which
became invokes!  This fixes PR57, tested by

04e6824a3f Publicize the type of FnAllocState.
Prototype option to save state in a global instead of as a Constant in
 the Module. (Turned off, for now, with the on/off switch welded in the off
 position. You get the idea.)

 AllocInfos to LLVM Constants.

51684bea99 Make this pass substantially stronger by having it delete dead return values
as well as arguments.  Now it can delete arguments and return values which are
only passed into other arguments or are returned, if they are dead.  This causes
it to delete several hundred extra args/retvals from the C++ hello world program,
shrinking it by about 2K.
