cf747b7398 Fix issue with SCCs getting added to the call graph multiple times.
Don't create the SCC finder for each root - we end up losing the state
of what we've already visited.

6a695f3099 Move DeadFunctionElimination to using the new call graph.
The old call graph remains, but the new call graph can obtained by
calling getCallGraph() on the analysis pass.

I'll move the few other passes that use the call graph over soon and
then rip out the old call graph.

No diffs in the stdlib.

36365d79df In the new call graph, find the SCCs in bottom-up order.
With this change we generate the SCCs in the call graph (for the kinds
of calls we currently recognize) in bottom-up, which we can then
iterate over directly or in reverse for invocation- and
reverse-invocation-order traversal of the call graph.

(This still isn't hooked up - but will be after some dumping routines
and verification of the output).

3494d6ab39 Track call graph roots with a SmallVector rather than DenseSet.
This will allow us to search in the order the roots are added which
should improve stability of our output. There is also an ordinal on each
node that we can use to choose order of traversing edges at a given call
site.

dee10cb164 Update the new call graph so that edges have sets of call graph nodes.
Previously we tracked a set of functions that could be called from a given
call site. Now we track a set of call graph nodes (each of which
represents a callable function). As a result we now create call graph
nodes for declarations rather than just definitions.

2719a13114 Add statistic to call graph builder for calls to builtins.
Add a statistic to the new call graph to track calls to builtins (for
which we do not have a call graph node or edge).

a3350db69c Add statistics to call graph construction.
Also stub out some of the cases we'll need to handle to build a more
complete call graph.

34a1050222 Add data structures for a new, more detailed, call graph.
This is not yet hooked up. I want to add a dumper and some tests, and
need to implement code to do invocation- and reverse-invocation-ordering
over the SCCs of the call graph before it can fully replace the existing
code.

This call graph has edges for each call site, so it's really a
multigraph. Each call site tracks the set of functions that can be
called from that point. Currently that set is always a singleton since
we only handle applies of direct function_refs (like the existing call
graph). In time it will be expanded to handle other types of function
application.
