e95c76b65e Get rid of one more non-DebugLoc getNode and 
its corresponding getTargetNode.  Lots of
caller changes.

475c341202 Fix a crasher: we need to check that the function is non-null before using it!

acbec98578 Refactor my previous change to maintain the distinction between AliasAnalysis and BasicAliasAnalysis. This involves some wider changes because it 
folds away some never-used methods.

6a938dd9e7 isAsCheapAsMove instructions can have register src operands. Check if they are really re-materializable. 
This fixes sse.expandfft and sse.stepfft.

compilers that don't support those flags.  This hopefully will help
gcc 3.X compile this code.  http://llvm.org/PR3487

134778fae1 Revert the previous commit. It seems it didn't 
really solve the problem.  Also it changed the
name from libLLVMgold to LLVMgold (correcting
the name resulted in the original problem
suddenly reappearing).

9ae3dee83e Stop llvm-config thinking that there are circular 
dependencies between libraries due to __dso_handle
when doing "make install".  I don't know what the
LINK_COMPONENTS stuff is about, so I left it alone.

d8f77bbc07 if we have a large GEP offset on a 32-bit or other target, make 
sure to print the value properly sext'd to the right pointer size.

902d570061 Pre-alloc splitting needs to be more careful to avoid inserting spills/restores 
between call frame setup/restore points.  Unfortunately, this regresses 
code size a bit, but at least it's correct now!

7c25f31e98 It's not obvious, but lto_module_create_from_memory doesn't need to use the 
buffer after it creates the Module. Thus, we don't need to store this pointer
in claimed_file.

66f10b55ed New feature: add support for target intrinsics being defined in the 
target directories themselves.  This also means that VMCore no longer
needs to know about every target's list of intrinsics.  Future work
will include converting the PowerPC target to this interface as an
example implementation.

83f8f82e8a Avoids generating a legalization assert for the case where a vector type is legal 
but when legalizing the operation, we split the vector type and generate a library
call whose type needs to be promoted. For example, X86 with SSE on but MMX off, 
a divide v2i64 will be scalarized to 2 calls to a library using i64.
