5b8615fcbd We need to guard reads of the AbstractTypeUsers list, as well as writes to it. While it would be nice to use a R/W lock here, 
we can't, because it HAS to be recursive.

c40f3f2752 Improve the Win32 reader-writer lock implementation by making it just a normal 
lock.  This is obviously bad, but at least it's threadsafe!  If you know how
to improve this in a pre-Vista friendly well, patches welcome!

The problem is replaceAllUsesWith asserts for type mismatch here. Try attached .bc with llvm-ld.

assert(New->getType() == getType() &&
        "replaceAllUses of value with new value of different type!");

Since stack is always on address space zero, I don't think that type of GV in a different address space is ever going to match.
The other way is to allow replaceAllUsesWith to ignore address spaces while comparing types. (do we have  a way to do that ?).
But then such an optimization may fail the entire idea of user wanting to place a variable into different memory space. The original idea of user might be to save on the stack space (data memory) and hence he asked the variable to be placed into different memory space (program memory). So the best bet here is to deny this optimization by checking

GV->getType()->getAddressSpace() == 0.

3c85f09f57 Remove support for building LLVM libraries into "relinked" 
object files.  Now we always build LLVM libraries into archives (.a files).

This makes the 'make' build work more like the cmake build, among other
things.  Doing this exposed some latent circular library dependencies, so
I think that llvm-config wasn't quite right for .o files anyway.

f5291553f2 Introduce new headers whose inclusion forces linking and 
initialization of all targets (InitializeAllTargets.h) or assembler
printers (InitializeAllAsmPrinters.h). This is a step toward the

archives.
