Rematerialize nodes from the globals graph into the current graph
...
after all callees are inlined into the current graph.
NOTE: There's also a major bug fix for the BU pass in DataStructure.cpp,
which ensures that resolvable indirect calls are not moved out to the
globals graph, so that they are eventually inlined (if possible).

(1) Rematerialize nodes from the globals graph into the current graph
...
after all callers are inlined into the current graph.
(2) Optimize the way a graph is inlined into its callees in the TD phase:
(a) Use DSGraph::cloneReachableSubgraph to clone only a subgraph at
each call site, for faster inlining.
(b) Clone separately for the same callee at different call sites,
since only the reachable subgraph is being cloned, not the entire
caller graph.
llvm-svn: 7188

Vikram S. Adve
dce6694ff4
Implement 2 important changes: (1) rematerialization from the globals graph,
...
and (2) faster inlining by cloning only reachable nodes. In particular:
(1) Added DSGraph::cloneReachableSubgraph and DSGraph::cloneReachableNodes
to clone the subgraph reachable from a set of root nodes, into the
current graph, merging the global nodes into thos in the current graph.
The TD pass now uses this for faster inlining, and so does the
next function.
(2) Added DSGraph::updateFromGlobalGraph() to rematerialize nodes from the
globals graph into the current graph in both BU and TD passes.
(3) `I' flags are removed from all nodes in the globals graph, because they
are difficult to maintain correctly and are not needed anyway.
(4) Aux. function calls are only removed to the globals graph if they
will never be resovled. (This is what fixed gap.) The immediate
reason is that if we took these out of a function (and moved them to
the globals graph) we would need to rematerialize these nodes into the
function graph for every function in the BU pass. The longer term
problem is that we would need to find a way to remove them from the
globals graph iff they have been resolved on all paths through the
call graph.

Fix two bugs:

* The globals vector was getting broken and unsorted, this caused vortex
to get badly pessimized
* Node offset handling was being handled really poorly, and in particular
we were not merging types with offsets right. This causes several graphs
to be non-merged.
