although in this case we probably just run a risk of duplicating work;
I can't think of how this could cause a bug.

using directives, and fix a bug thereby exposed:  since we're playing
tricks with pointers, we need to make certain we're always using the same 
pointers for things.
Also tweak an existing error message.

Update computeArraySize() to use ComputeMultiple() to determine the array size associated with a malloc; also extend PerformHeapAllocSRoA() to check if the optimized malloc's arg had its highest bit set, so that it is safe for ComputeMultiple() to look through sext instructions while determining the optimized malloc's array size

Add ComputeMultiple() analysis function that recursively determines if a Value V is a multiple of unsigned Base

This is reasonable because people know what they are doing when they 
intentionally dereference the pointer.
So now we only emit warning when a pointer variable is use literally.

Add the most derived vtable pointer to the VTT.

This is a pretty minimal test case;  I'll make a better one later.

When trying to assign a regular string literal to an Objective-C 'id' type or a pointer to an NSString, emit a code insertion hint that turns it into an Objective-C string. For example:

@class NSString;

@interface Test
+ (void)test:(NSString *)string;
@end

void g(NSString *a);

void f() {
  NSString *a = "Foo";
  g("Foo");
  [Test test:"Foo"];
}

will produce

t.m:10:17: warning: incompatible pointer types initializing 'char [4]', expected 'NSString *'
  NSString *a = "Foo";
                ^~~~~
                @
t.m:11:5: warning: incompatible pointer types passing 'char [4]', expected 'NSString *'
  g("Foo");

If a function with a default argument is redefined and the new function also has a defualt argument then add a fixit hint that removes the default argument. Fixes PR5444.

just one level deep.  On the testcase we go from getting this:

F1:                                               ; preds = %T2
  %F = and i1 true, %cond                         ; <i1> [#uses=1]
  br i1 %F, label %X, label %Y

to a fully threaded:

F1:                                               ; preds = %T2
  br label %Y


This changes gets us to the point where we're forming (too many) switch 
instructions on doug's strswitch testcase.
