912095beca Expand fcopysign to a series of bitwise of operations when it's profitable to 
do so.

bcca3405bd Legalizer doesn't do an ANY_EXTEND if we don't ask for one so make sure 
that we default to an ANY_EXTEND if no parameter attribute is set on the
result value of a function.

376dd212f9 Restore previous behavior of defaulting to ZEXT. This works around two 
things: (1) preventing PR1071 and (2) working around missing parameter
attributes for bool type. (2) will be fixed shortly. When PR1071 is fixed,
this patch should be undone.

8c57dfb1ae Two changes: 
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.

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.

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.
