John McCall 2fbe92cc24 Perform the receiver-expression transformations regardless of
whether we already have a method.  Fixes a bug where we were
failing to properly contextually convert a message receiver
during template instantiation.

As a side-effect, we now actually perform correct method lookup
after adjusting a message-send to integral or non-ObjC pointer
types (legal outside of ARC).

Chandler Carruth 55fc873017 Sort all of Clang's files under 'lib', and fix up the broken headers
uncovered.

This required manually correcting all of the incorrect main-module
headers I could find, and running the new llvm/utils/sort_includes.py
script over the files.

I also manually added quite a few missing headers that were uncovered by
shuffling the order or moving headers up to be main-module-headers.

John McCall b8a8de316d Accept and pass arguments to __unknown_anytype in argument
positions of Objective-C methods.

It is possible to recover a lot of type information about
Objective-C methods from the reflective metadata for their
implementations.  This information is not rich when it
comes to struct types, however, and it is not possible to
produce a type in the debugger's round-tripped AST which
will really do anything useful during type-checking.
Therefore we allow __unknown_anytype in these positions,
which essentially disables type-checking for that argument.
We infer the parameter type to be the unqualified type of
the argument expression unless that expression is an
explicit cast, in which case it becomes the type-as-written
of that cast.

Jordan Rose 535a5d001b Allow objc_requires_super to be used to check class methods as well.
Also, unify ObjCShouldCallSuperDealloc and ObjCShouldCallSuperFinalize.
The two have identical behavior and will never be active at the same time.

There's one last simplification now, which is that if we see a call to
[super foo] and we are currently in a method named 'foo', we will
/unconditionally/ clear the ObjCShouldCallSuper flag, rather than check
first to see if we're in a method where calling super is required. There's
no reason to pay the extra lookup price here.

Jordan Rose 7fffce781e -Warc-repeated-use-of-weak: Check messages to property accessors as well.
Previously, [foo weakProp] was not being treated the same as foo.weakProp.
Now, for every explicit message send, we check if it's a property access,
and if so, if the property is weak. Then for every assignment of a
message, we have to do the same thing again.

This is a potentially expensive increase because determining whether a
method is a property accessor requires searching through the methods it
overrides. However, without it -Warc-repeated-use-of-weak will miss cases
from people who prefer not to use dot syntax. If this turns out to be
too expensive, we can try caching the result somewhere, or even lose
precision by not checking superclass methods. The warning is off-by-default,
though.

Jordan Rose 1e4691b9d8 Rename ObjCMethodDecl::isSynthesized to isPropertyAccessor.
This more accurately reflects its use: this flag is set when a method
matches the getter or setter name for a property in the same class,
and does not actually specify whether or not the definition of the method
will be synthesized (either implicitly or explicitly with @synthesize).

This renames the setter and backing field as well, and changes the
(soon-to-be-obsolete?) XML dump format to use 'property_accessor'
instead of 'synthesized'.

Anna Zaks e61354b274 Consolidate ObjC lookupPrivateMethod methods from Sema and DeclObjC.
Also, fix a subtle bug, which occurred due to lookupPrivateMethod
defined in DeclObjC.h not looking up the method inside parent's
categories.

Note, the code assumes that Class's parent object has the same methods
as what's in the Root class of a the hierarchy, which is a heuristic
that might not hold for hierarchies which do not descend from NSObject.
Would be great to fix this in the future.

* Primarily fixed \param commands with names not matching any actual

  just of fixing up the parameter name in the \param to match the code,
  in some it means deleting obsolete documentation and occasionally it
  means documenting the parameter that has replaced the older one that
  was documented, which sometimes means some simple reverse-engineering
  of the docs from the implementation;
* Fixed \param ParamName [out] to the correct format with [out] before
  the parameter name;
* Fixed some \brief summaries.

John McCall 260611a325 Restructure how the driver communicates information about the
target Objective-C runtime down to the frontend:  break this
down into a single target runtime kind and version, and compute
all the relevant information from that.  This makes it
relatively painless to add support for new runtimes to the
compiler.  Make the new -cc1 flag, -fobjc-runtime=blah-x.y.z,
available at the driver level as a better and more general
alternative to -fgnu-runtime and -fnext-runtime.  This new
concept of an Objective-C runtime also encompasses what we
were previously separating out as the "Objective-C ABI", so
fragile vs. non-fragile runtimes are now really modelled as
different kinds of runtime, paving the way for better overall
differentiation.

As a sort of special case, continue to accept the -cc1 flag
-fobjc-runtime-has-weak, as a sop to PLCompatibilityWeak.

I won't go so far as to say "no functionality change", even
ignoring the new driver flag, but subtle changes in driver
semantics are almost certainly not intended.

Argyrios Kyrtzidis f5343ff93a Allow objc @() syntax for enum types.
Previously we would reject it as illegal using a value of

Jordy Rose 3eda6fa901 Only check NSArray/NSDictionary boxing method params once.
Once we've found a "good" method, we don't need to check its argument types

caching the method we first looked up.)
