3fb2b1ede3 Clean up LSDA name generation and use for SJLJ exception handling. This 
makes an eggregious hack somewhat more palatable. Bringing the LSDA forward
and making it a GV available for reference would be even better, but is
beyond the scope of what I'm looking to solve at this point.

Objective C++ code could generate function names that broke the previous
scheme. This fixes that.

4221489908 Extend the ValuesAtScope cache to cover all expressions, not just 
SCEVUnknowns, as the non-SCEVUnknown cases in the getSCEVAtScope code
can also end up repeatedly climing through the same expression trees,
which can be unusably slow when the trees are very tall.

Also, add a quick check for SCEV pointer equality to the main
SCEV comparison routine, as the full comparison code can be expensive
in the case of large expression trees.

These fix compile-time problems in some pathlogical cases.

2cd5155c0e Free the constants that have no uses in ~LLVMContext. 
This fixes leaks from LLVMContext in multithreaded apps.
Since constants are only deleted if they have no uses, it is safe to not delete
a Module on shutdown, as many single-threaded tools do.
Multithreaded apps should however delete the Module before destroying the
Context to ensure that there are no leaks (assuming they use a different context
for each thread).

be577659d3 Step #1 to giving Callgraph some sane invariants. The problems with callgraph 
stem from the fact that we have two types of passes that need to update it:

1. callgraphscc and module passes that are explicitly aware of it
2. Functionpasses (and loop passes etc) that are interlaced with CGSCC passes
   by the CGSCC Passmgr.

In the case of #1, we can reasonably expect the passes to update the call
graph just like any analysis.  However, functionpasses are not and generally
should not be CG aware.  This has caused us no end of problems, so this takes
a new approach.  Logically, the CGSCC Pass manager can rescan every function 
after it runs a function pass over it to see if the functionpass made any 
updates to the IR that affect the callgraph.  This allows it to catch new calls
introduced by the functionpass.

In practice, doing this would be slow.  This implementation keeps track of
whether or not the current scc is dirtied by a function pass, and, if so, 
delays updating the callgraph until it is actually needed again.  This was
we avoid extraneous rescans, but we still have good invariants when the
callgraph is needed.

Step #2 of the "give Callgraph some sane invariants" is to change CallGraphNode
to use a CallBackVH for the callsite entry of the CallGraphNode.  This way
we can immediately remove entries from the callgraph when a FunctionPass is
active instead of having dangling pointers.  The current pass tries to tolerate
these dangling pointers, but it is just an evil hack.

This is related to PR3601/4835/4029.  This also reverts r80541, a hack working
around the sad lack of invariants.
