45c7c69c77 fix PowerPC/2007-01-04-ArgExtension.ll, a bug handling K&R prototypes with 
the recent signless changes.

87c68ceb32 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.

92c52fe025 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.

dda168599d 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.

f6bd59ba81 Convert the last uses of CastInst::createInferredCast to a normal cast

rework the hacks that had us passing OStream in. We pass in std::ostream*

2f7cae1f57 Fix a long-standing spiller bug: 
If a spillslot value is available in a register, and there is a noop copy that
targets that register, the spiller correctly decide not to invalidate the
spillslot register.

However, even though the noop copy does not clobbers the value. It does start a
new intersecting live range. That means the spillslot register is available for
use but should not be reused for a two-address instruction modref operand which
would clobber the new live range.

When we remove the noop copy, update the available information by clearing the
canClobber bit.

75b41e03f6 - 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,

returns the result of the expanded source operand.
