a specialized pass that it not likely to be generally useful.

fix memory leak in pass manager when adding an analysis pass that already existed. as pass manager takes ownership of the added passes, it has to delete the pass if it isnt added to the pass list
tweak the opt tool so that it doesnt access a Pass after the ownership was taken by the pass manager

  "getOrInsertFunction" in that it either adds a new declaration of the global
  and returns it, or returns the current one -- optionally casting it to the
  correct type.
- Use the new getOrInsertGlobal in the stack protector code.
- Use "splitBasicBlock" in the stack protector code.

llvm-svn: 58727

First pass at checking for the creation of a new join point when doing pre-alloc splitting.  This is not turned on yet.

- Use enums instead of magic numbers.

- Rework algorithm to use the bytes size from the target to determine when to
  emit stack protectors.

- Get rid of "propolice" in any comments.

- Renamed an option to its expanded form.

- Other miscellanenous changes.

More changes will come after this.

Some cleanup of the cast checkers. Don't canonicalize types when not needed. Use distinct diagnostics for distinct errors.

Add a new expression class, ObjCSuperExpr, to handle the Objective-C 'super'. Remove ObjCThis from PredefinedExpr
