Fariborz Jahanian 283bf89506 Objective-C. After providing a fix-it for a
cstring, converted to NSString, produce the
matching AST for it. This also required some
refactoring of the previous code. // rdar://14106083

Fariborz Jahanian d838bba59b objective-C: clang, following gcc, warns on
use of stand-alone protocol as type and uses
id<proto>. Modify warning to say what compiler

Douglas Gregor 5ff4e98c61 Introduce a Fix-It for the "missing sentinel" warning, adding an
appropriate sentinel at the end of the argument list. Also, put the
sentinel warnings under -Wsentinel. Fixes <rdar://problem/8764236>.

Nick Lewycky 784fad7a41 Teach clang -fixit to modify files in-place, or -fixit=suffix to create new
files with the additional suffix in the middle.

Douglas Gregor b10646d4ce Improve diagnostics like "initializing <type> from an expression of
type..." with "initializing <type> with an expression of type...",
which reads better. Thanks to John for the improved wording.

Douglas Gregor c68e140657 Improve diagnostics when we fail to convert from a source type to a
destination type for initialization, assignment, parameter-passing,
etc. The main issue fixed here is that we used rather confusing
wording for diagnostics such as

t.c:2:9: warning: initializing 'char const [2]' discards qualifiers,
      expected 'char *' [-pedantic]
  char *name = __func__;
        ^      ~~~~~~~~

We're not initializing a 'char const [2]', we're initializing a 'char
*' with an expression of type 'char const [2]'. Similar problems
existed for other diagnostics in this area, so I've normalized them all
with more precise descriptive text to say what we're
initializing/converting/assigning/etc. from and to. The warning for
the code above is now:

t.c:2:9: warning: initializing 'char *' from an expression of type
      'char const [2]' discards qualifiers [-pedantic]
  char *name = __func__;
        ^      ~~~~~~~~

Fixes <rdar://problem/7447179>.

Daniel Dunbar 8fbe78f6fc Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.
- This is designed to make it obvious that %clang_cc1 is a "test variable"
   which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
   can be useful to redefine what gets run as 'clang -cc1' (for example, to set
   a default target).

Anders Carlsson ace5d07e50 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 *'
  [Test test:"Foo"];
             ^~~~~
