Move the dynamic linking functionality of the llvm-rtdyld program into an
ExecutionEngine support library. Update llvm-rtdyld to just load an object
file into memory, use the library to process it, then run the _main()
function, if one is found.

Improve crash recovery cleanup to recovery CompilerInstances during crash recovery.  This was a huge resource "root" during crashes.

This change requires making a bunch of fundamental Clang structures (optionally) reference counted to allow correct
ownership semantics of these objects (e.g., ASTContext) to play out between an active ASTUnit and CompilerInstance
object.

This is a helper class that will make it easier to say which InstAliases can be
