10f1e4dda8 When suggesting a typo correction for an @implementation without a
corresponding @interface, provide a note showing which interface we're
referring to. This note has the fix-it hint on it.

Also, don't automatically apply fix-it hints for notes. They're meant
to express fix-its that would change semantics.

ccecc1bb43 Fix marking of virtual members for nested classes whose first non-pure virtual function has a body inlined in the class

859f0ae041 Make sure that the key-function computation produces the correct
result for a nested class whose first non-pure virtual member function
has an inline body. Previously, we were checking for the key function
before we had seen the (delayed) inline body.

fd0b2f8fe4 Improve the diagnostics used to report implicitly-generated class members
as parts of overload sets.  Also, refer to constructors as 'constructors'
rather than functions.

70aa5391dd Significantly rework the calculation of effective integer-expression ranges
for -Wsign-compare and -Wconversion, and use that coordinated logic to drive
both diagnostics.  The new logic works more transparently with implicit
conversions, conditional operators, etc., as well as bringing -Wconversion's
ability to deal with pseudo-closed operations (e.g. arithmetic on shorts) to
-Wsign-compare.

Fixes PRs 5887, 5937, 5938, and 5939.

0a0f04dcb9 Make our marking of virtual members functions in a class be
deterministic and work properly with templates. Once a class that
needs a vtable has been defined, we now do one if two things:

  - If the class has no key function, we place the class on a list of
    classes whose virtual functions will need to be "marked" at the
    end of the translation unit. The delay until the end of the
    translation unit is needed because we might see template
    specializations of these virtual functions.
  - If the class has a key function, we do nothing; when the key
    function is defined, the class will be placed on the
    aforementioned list.

At the end of the translation unit, we "mark" all of the virtual
functions of the classes on the list as used, possibly causing
template instantiation and other classes to be added to the
list. This gets LLVM's lib/Support/CommandLine.cpp compiling again.

e51136ee05 Per offline discussion with Doug, don't perform typo correction when we have encountered a fatal error. On some files that are woefully wrong (missing headers) this can cause a 3x slowdown in some cases when parsing the file. It makes sense not to perform typo correction in this case because after a fatal error diagnostics will either be suppressed or not really make any sense.

a318efd1f2 Improve key-function computation for templates. In particular:
- All classes can have a key function; templates don't change that.
  non-template classes when computing the key function.
  - We always mark all of the virtual member functions of class
  template instantiations. 
  - The vtable for an instantiation of a class template has weak
  linkage. 

We could probably use available_externally linkage for vtables of
classes instantiated by explicit instantiation declarations (extern
templates), but GCC doesn't do this and I'm not 100% that the ABI
permits it.

40f7a007e9 When declaring an Objective-C implementation without a corresponding
interface, suggest correction of typos. For example, given:

  @interface NSString
  @end

  @implementation NSstring
  @end

we'll warn with:

t.m:4:19: warning: cannot find interface declaration for 'NSstring';
    did you mean 'NSString'?
  @implementation NSstring
                  ^

However, since this is just a warning, we don't provide a fix-it
hint. Good idea, Ted!

35b0bac8c5 Implement typo correction for a variety of Objective-C-specific
constructs:

  - Instance variable lookup ("foo->ivar" and, in instance methods, "ivar")
  - Property name lookup ("foo.prop")
  - Superclasses
  - Various places where a class name is required
  - Protocol names (e.g., id<proto>)

This seems to cover many of the common places where typos could occur.

2d435306e5 Typo correction for type names when they appear in declarations, e.g., given
tring str2;

we produce the following diagnostic + fix-it:

typo.cpp:15:1: error: unknown type name 'tring'; did you mean 'string'?
  tring str2;
  ^~~~~
  string


To make this really useful, we'll need to introduce typo correction in
many more places (wherever we do name lookup), and implement
declaration-vs-expression heuristics that cope with typos
better. However, for now this will handle the simple cases where we
already get good "unknown type name" diagnostics.

The LookupVisibleDecls functions are intended to be used by code
completion as well as typo correction; that refactoring will happen
later.

c712ce1b60 More fixes to the handling of CVR-comparisons on array types. Adds a method to
QualType to get CVR-qualifiers through array types, and switches the primary
comparison methods to use it. This may allow simplifying some of the callers of
getUnqualifiedArrayType.

Also fix the normalizing of CV-qualification during template deduction to
normalize through arrays and allow a more qualified deduced array type. This
fixes PR5911.
