a72f3a387a Eliminated the CompletedNodes argument to the cloneReachable* methods. This 
map was only used to implement a marginal GlobalsGraph optimization, and it
actually slows the analysis down (due to the overhead of keeping it), so just
eliminate it entirely.

7348bd20b1 It doesn't make sense for one side to be const, but not the other.

5f0e00c8b2 Remove const qualifier (all Value*'s are nonconst in DSA, so it's not clear 
why this one was)

38664cbb8b To materialize a module, you need to know what functions NEED to be read and 
which ones don't, which is state that the parent class doesn't know without
knowing the implementation. Let the children classes implement
materializeModule().

61db3621bd Use a list instead of a vector to store intervals. This will be needed 
when we join intervals and one of the two will need to be removed.

599ab961c4 Add new ConstantArray::isString(), as the conditions for using getString() 
are complex enough to check that it should be a seperate method.

While I'm here, improve ConstantArray::getNullValue a bit, though the
FIXME is still quite valid.

bcd7372d19 The only clients of the slot calculator are now the asmwriter and bcwriter. 
Since this really only makes sense for these two, change hte instance variable
to reflect whether we are writing a bytecode file or not.  This makes it
reasonable to add bcwriter specific stuff to it as necessary.

LiveVariables::HandlePhysRegDef private they use information that is
not in memory when LiveVariables finishes the analysis.

d11cffdfc6 Add new ExecutionEngine::getGlobalValueAtAddress method, which can efficiently 
turn a memory address back into the LLVM global object that starts at that
address.  Note that this won't cause any additional datastructures to be built
for clients of the EE that don't need this information.

fc01aac4d8 Add coalescing to register allocator. A hint is added to each interval 
which denotes the register we would like to be assigned to (virtual or
physical). In register allocation, if this hint exists and we can map
it to a physical register (it is either a physical register or it is a
virtual register that already got assigned to a physical one) we use
that register if it is available instead of a random one in the free
pool.
