Change the interface to Module::getOrInsertFunction to be easier to use,to resolve PR1088, and to help PR411.

attributes for bool type. (2) will be fixed shortly. When PR1071 is fixed,
this patch should be undone.

1. Switch expression and cases are compared signed and are sign extended.
2. For function results needing extended, do SIGN_EXTEND if the SExtAttribute
   is set and ZERO_EXTEND if the ZExtAttribute is set, otherwise just let
   the Legalizer do ANY_EXTEND.
This fixes the recent regression in kimwitu++ and probably the llvm-gcc
bootstrap issue we had today.

Three changes:
1. Convert signed integer types to signless versions.
2. Implement the @sext and @zext parameter attributes. Previously the
   type of an function parameter was used to determine whether it should
   be sign extended or zero extended before the call. This information is
   now communicated via the function type's parameter attributes.
3. The interface to LowerCallTo had to be changed in order to accommodate
   the parameter attribute information. Although it would have been
   convenient to pass in the FunctionType itself, there isn't always one
   present in the caller. Consequently, a signedness indication for the
   result type and for each parameter was provided for in the interface
   to this method. All implementations were changed to make the adjustment
   necessary.

This patch removes the SetCC instructions and replaces them with the ICmp
and FCmp instructions. The SetCondInst instruction has been removed and
been replaced with ICmpInst and FCmpInst.

knowledge of signedness out closer to where it can be determined properly
