0893d5847f Move some constant folding functions into LLVMAnalysis since they are used 
by Analysis and Transformation passes.

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.

into: malloc int, (2*X)

4c9dae5fdb Promote cases like cast (malloc sbyte, 100) to int* into 
(malloc [25 x int]) directly without having to convert to
(malloc [100 x sbyte]) first.

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))

and stuff.

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

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.

77f228f586 Handle allocations that, even after removing dead uses, still have more than 
one use (but one is a cast).  This handles the very common case of:

 X = alloc [n x byte]
 Y = cast X to somethingbetter
 seteq X, null

In order to avoid infinite looping when there are multiple casts, we only
allow this if the xform is strictly increasing the alignment of the
allocation.

a295128ce5 Fix a bug where we would 'promote' an allocation from one type to another 
where the second has less alignment required.  If we had explicit alignment
support in the IR, we could handle this case, but we can't until we do.

3806b84861 Before promoting a malloc type, remove dead uses. This makes instcombine 
more effective at promoting these allocations, catching them earlier in the
compile process.
