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.

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");
^~~~~
@
t.m:12:14: warning: incompatible pointer types sending 'char [4]', expected 'NSString *'

make jump threading recursively simplify expressions instead of doing it

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.
