47857812e2 For PR950: 
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.

5c7e326585 Added an automatic cast to "std::ostream*" etc. from OStream. We then can 
rework the hacks that had us passing OStream in. We pass in std::ostream*
instead, check for null, and then dispatch to the correct print() method.

7b2b5c846c - When expanding a bit_convert whose src operand is also to be expanded and 
its expansion result type is equal to the result type of the bit_convert,
e.g. (i64 bit_convert (f64 op)) if FP is not legal
returns the result of the expanded source operand.
- Store f32 / f64 may be expanded to a single store i32/i64.

3da59db637 For PR950: 
The long awaited CAST patch. This introduces 12 new instructions into LLVM
to replace the cast instruction. Corresponding changes throughout LLVM are
provided. This passes llvm-test, llvm/test, and SPEC CPUINT2000 with the
exception of 175.vpr which fails only on a slight floating point output
difference.

First in a series of patches to convert SetCondInst into ICmpInst and
FCmpInst using only two opcodes and having the instructions contain their
predicate value. Nothing uses these classes yet. More patches to follow.

03fa6ea402 - When performing pre-/post- indexed load/store transformation, do not worry 
about whether the new base ptr would be live below the load/store. Let two
  address pass split it back to non-indexed ops.
