Do not warn when property declared in class's protocol will be auto-synthesized
by its uper class implementation because super class has also declared this
property while this class has not. Continue to warn if current class
has declared the property also (because this declaration will not result
in a 2nd synthesis).

This patch adds support for the msvc pragmas section, bss_seg, code_seg,
const_seg and data_seg as well as support for __declspec(allocate()).
Additionally it corrects semantics and adds diagnostics for
__attribute__((section())) and the interaction between the attribute
and the msvc pragmas and declspec. In general conflicts should now be
well diganosed within and among these features.
In supporting the pragmas new machinery for uniform lexing for
msvc pragmas was introduced. The new machinery always lexes the
entire pragma and stores it on an annotation token. The parser
is responsible for parsing the pragma when the handling the
annotation token.
There is a known outstanding bug in this implementation in C mode.
Because these attributes and pragmas apply _only_ to definitions, we
process them at the time we detect a definition. Due to tentative
definitions in C, we end up processing the definition late. This means
that in C mode, everything that ends up in a BSS section will end up in
the _last_ BSS section rather than the one that was live at the time of
tentative definition, even if that turns out to be the point of actual
definition. This issue is not known to impact anything as of yet
because we are not aware of a clear use or use case for #pragma bss_seg
but should be fixed at some point.

Drive-by fixing some incorrect types where a for loop would be improperly using ObjCInterfaceDecl::protocol_iterator. No functional changes in these cases.

This is a reapplication of r203236 with modifications to the definition of attrs() and following the new style guidelines on auto usage.

In particular, if we see an @property within the @interface of a class
conforming to a protocol with this attribute, we treat that as
if the implementation were available, per the rules of default
property synthesis.

We're going to extend DiagnoseUnimplementedProperties shortly to look for more cases
that aren't handled by default property synthesis.

A return type is the declared or deduced part of the function type specified in
the declaration.
A result type is the (potentially adjusted) type of the value of an expression
that calls the function.
Rule of thumb:
* Declarations have return types and parameters.
* Expressions have result types and arguments.

Additionally, remove the optional nature of the spelling list index when creating attributes. This is supported by table generating a Spelling enumeration when the spellings for an attribute are distinct enough to warrant it.

Previously, the synthesized AST contained an rvalue DeclRefExpr for 'self'.
Now, it has an lvalue DeclRefExpr wrapped in an lvalue-to-rvalue
ImplicitCastExpr, which is what's generated when an ivar access is written
in the source.
No (intended) functionality change.

property has the naming convention that implies 'ownership'.
2) improve on diagnostic and make it property specific.
3) fix the line number in the case of default property
synthesis. // rdar://15757510

property declaration has a memory management
attribute (retain, copy, etc.). Sich properties
are usually overridden to become 'readwrite'
via a class extension (which require the memory
management attribute specified). In the absence of class
extension override, memory management attribute is
needed to produce correct Code Gen. for the
property getter in any case and this warning becomes
confusing to user. // rdar://15641300
