b6c408778a Optimize away cases like: 
%cast109 = cast uint %cast212 to short          ; <short> [#uses=1]
        %cast214 = cast short %cast109 to uint          ; <uint> [#uses=1]
        %cast215 = cast uint %cast214 to short          ; <short> [#uses=1]

a4184f9ab6 Fix: ConstantMerge/2002-09-23-CPR-Update.ll 
Basically, this bug boiled down to calling replaceUsesOfWith on a constant,
which changed it's shape in an illegal way.  This pass now goes through all
of the trouble neccesary to do the replacement on constants.

b9379750d9 Fix cwriter to not output FP constants in ascii, output them in hex instead. 
This fixes a number of FP precision problems, making the output of the
power benchmark closer to the right answer.

Unfortunately, this only addresses FP constants used directly in functions.
Constants referred to by global constants (such as an array of FP values)
aren't helped by this.  Until this happens power won't work.

af6a9e8fc4 Another change that doesn't affect functionality. Since we are only looking 
at types in the symbol table, only traverse the type plane, saving a loop nest.

ccb33335a3 Allow copy coalescing in more cases: if sum of node degrees is more than 
than #available regs, compute the sum excluding duplicates and if that
is less than #regs, go ahead and coalesce.

  Don't put default parameter values into .cpp files, it breaks 3.x compilers

  revision 1.1
  date: 2002/09/16 15:31:13;  author: vadve;  state: Exp;
  New preselection pass that specializes LLVM code for a target machine,
  while remaining in legal portable LLVM form and preserving type
  information and type safety.

c86c7ecdb5 Make sure that we abort if an error happens as early as neccesary. Before 
it was possible for the passmanager to continue running passes after the
verifier even if the module was not well formed.
