DAGUpdateListener object pointer instead of just returning a vector
of deleted nodes. This makes the interfaces more efficient (no more
allocating a vector [at least a malloc], filling it in, then walking
it) and more clean. This also allows the client to be notified of
nodes that are *changed* but not deleted.

SelectionDAG::ReplaceAllUsesWith to handle replacement of
an SDOperand with *any* sdoperand, not just one for a node with
a single result. Note that this has a horrible FIXME'd hack in it
to work around PR1975. This should be removed when PR1975 is fixed.

should be merged just like normal globals. This fixes this testcase
that Anders provided:
static struct s a;
static struct s *ap1 = &a;
static struct s a = { 10 };

Added ISD::DECLARE node type to represent llvm.dbg.declare intrinsic. Now the intrinsic calls are lowered into a SDNode and lives on through out the codegen passes.
For now, since all the debugging information recording is done at isel time, when a ISD::DECLARE node is selected, it has the side effect of also recording the variable. This is a short term solution that should be fixed in time.

Since this behavior is useful for most classes, we might consider adding a simple 3 method class that implements the behavior. Ted said that Boost has such a class.

and put the the next ObjcAtCatchStmt* as part of SubExprs. This fixes a bug with
iterating over the children of ObjcAtCatch, where the next @catch was not
properly being iterated over as a child.
Altered serialization of ObjCAtCatchStmt to reflect this new layout of
its subexpressions, and fixed an ownership issue with the next @catch not
being serialized as an owned pointer.

- Support @catch(...), rather than crash:-)
- Make sure all catch bodies get rewritten. This "fix" is really a workaround until the iterator for the "try" AST is fixed. Will fix this in a separate commit.

Fix Sema::ActOnInstanceMessage to correctly do things in terms of canonical
types, fixing bogus errors like:
NSDistantObject.m:10383:120: error: bad receiver type 'typeof((id<NSMutableCopying>)self)'
id mess = ({ id __inv__ = ((void *)0); id __mb__ = _NSMessageBuilder((id <NSMutableCopying>)self, &__inv__); (void)[(__typeof__((id <NSMutableCopying>)self))__mb__ mutableCopyWithZone:((void *)0)]; if (!objc_collecting_enabled()) object_dispose(__mb__); __inv__; });
llvm-svn: 46633
here I fix just one. The loop that rips through pointers should use
getAsPointerType() not static_cast<PointerType*> to get the pointee. This
fixes a crash on a large testcase.
