d6538108e8 Move some constant folding code shared by Analysis and Transform passes 
into the LLVMAnalysis library.
This allows LLVMTranform and LLVMTransformUtils to be archives and linked
with LLVMAnalysis.a, which provides any missing definitions.

b0f5adf975 1. Remove libraries no longer created from the list of libraries linked into the 
SparcV9 JIT.
2. Make LLVMTransformUtils a relinked object file and always link it before
   LLVMAnalysis.a.  These two libraries have circular dependencies on each
   other which creates problem when building the SparcV9 JIT.  This change
   fixes the dependency on all platforms problems with a minimum of fuss.

91450212d4 Add nodes for CondCodeSDNode and setcc, and add a bunch of pattern fragments 
to make it easy to use them.  This lets you write patterns like:

(set PRRC:$rd, (setne GPRC:$rS, imm:$SH))

c3ab5792e9 Correctly Expand or Promote FP_TO_UINT based on the capabilities of the 
machine.  This allows us to generate great code for i32 FP_TO_UINT now on
targets with 64 bit extensions.

98c5495992 Allow custom lowered FP_TO_SINT ops in the check for whether a larger 
FP_TO_SINT is preferred to a larger FP_TO_UINT.  This seems to be begging
for a TLI.isOperationCustom() helper function.
