26f0dd9021 This fixes a bug introduced in 72661, which can 
move loads back past a check that the load address
is valid, see new testcase.  The test that went
in with 72661 has exactly this case, except that
the conditional it's moving past is checking
something else; I've settled for changing that
test to reference a global, not a pointer.  It
may be possible to scan all the tests you pass and
make sure none of them are checking any component
of the address, but it's not trivial and I'm not
trying to do that here.

3bf7bd1297 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.

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.

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.
