31c36f02f2 Simplify the locking on the Constants tables, and make it more efficient, by pushing it into the ValueMap from the callers. 
Document those ValueMap functions that are _not_ locked, so that callers are aware that they need to do the locking themselves.

4f0ac58da1 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.

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.

6be926647d 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.
