from them.  This is a very common case, so it's worthwhile to handle efficiently.

Close out this long standing bug by removing the remaining overloaded
virtual functions in LLVM. The -Woverloaded-virtual option is now turned on.

pounding on Loop::contains (which is O(n) in the size of the loop), use a
sorted vector, which is O(log(N)) for each query.  This speeds up Duraid's
horrible testcase from ~72s to ~31s in a debug build.

target CG node.  This allows the inliner to properly update the callgraph
when using the pruning inliner.  The pruning inliner may not copy over all
call sites from a callee to a caller, so the edges corresponding to those
call sites should not be copied over either.

Refactor the Graph writing code to use a common implementation which is
now in lib/Support/GraphWriter.cpp. This completes the PR.

Do partial inlining in BU.  This resolves more call sites.  Also add options to merge in globals during recursion and to back annotate DSNodes when function pointers are resolved.  This makes PA work for a whole lot more things (unresolved call sites being what has been killing various DSA based passes)
