ObjCMethodDecl::findPropertyDecl: bail out early if not an instance method.

Currently, Objective-C does not support class properties, even though it
allows calling class methods with dot syntax.

No intended functionality change; purely optimization.

[libclang] Improve AST serialization done by ASTUnit::Save().

The ASTUnit needs to initialize an ASTWriter at the beginning of
parsing to fully handle serialization of a translation unit that
imports modules. Do this by introducing an option to enable it, which
corresponds to CXTranslationUnit_ForSerialization on the C API side.

-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.

-Warc-repeated-use-of-weak: Don't warn on a single read followed by writes.

This is a "safe" pattern, or at least one that cannot be helped by using
a strong local variable. However, if the single read is within a loop,
it should /always/ be treated as potentially dangerous.
