4d4dcc8ed7 When synthesizing Objective C records, give the synthetic fields public 
access.  Fixes an assertion.

Fixes rdar://problem/7927811.  Too lazy to reduce a test case.

c4df407604 Keep track of the actual storage specifier written on a variable or 
function declaration, since it may end up being changed (e.g.,
"extern" can become "static" if a prior declaration was static). Patch
by Enea Zaffanella and Paolo Bolzoni.

c50c27cca8 the big refactoring bits of PR3782. 
This introduces FunctionType::ExtInfo to hold the calling convention and the
noreturn attribute. The next patch will extend it to include the regparm
attribute and fix the bug.

fc83aa04db Unconditionally support block introspection data in a new field at the end 
of the block descriptor field.  This field is the ObjC style @encode
signature of the implementation function, and was to this point
conditionally provided in the block literal data structure.  That
provisional support is removed.

Additionally, eliminate unused enumerations for the block literal flags field.
The first shipping ABI unconditionally set (1<<29) but this bit is unused
by the runtime, so the second ABI will unconditionally have (1<<30) set so
that the runtime can in fact distinguish whether the additional data is
present or not.

999ddbcf8e Patch to remove arbitrary imporation of 'self' into 
a block without it being used. This causes over release
of objects in certain runtime-senitive apps.

ab26cfa58d Standardize the parsing of function type attributes in a way that 
follows (as conservatively as possible) gcc's current behavior:  attributes
written on return types that don't apply there are applied to the function
instead, etc.  Only parse CC attributes as type attributes, not as decl attributes;
don't accepet noreturn as a decl attribute on ValueDecls, either (it still
needs to apply to other decls, like blocks).  Consistently consume CC/noreturn
information throughout codegen;  enforce this by removing their default values
in CodeGenTypes::getFunctionInfo().

40775003e6 Roll out ASTContext::getTypeSizeInChars(), replacing instances of 
"ASTContext::getTypeSize() / 8". Replace [u]int64_t variables with CharUnits
ones as appropriate. 

Also rename RawType, fromRaw(), and getRaw() in CharUnits to QuantityType, 
fromQuantity(), and getQuantity() for clarity.

9dd450bb78 Change all the Type::getAsFoo() methods to specializations of Type::getAs(). 
Several of the existing methods were identical to their respective
specializations, and so have been removed entirely.  Several more 'leaf'
optimizations were introduced.

The getAsFoo() methods which imposed extra conditions, like
getAsObjCInterfacePointerType(), have been left in place.

60ed560428 Introduce DeclaratorDecl and pass DeclaratorInfo through the Decl/Sema interfaces. 
DeclaratorDecl contains a DeclaratorInfo* to keep type source info.
Subclasses of DeclaratorDecl are FieldDecl, FunctionDecl, and VarDecl.
EnumConstantDecl still inherits from ValueDecl since it has no need for DeclaratorInfo.

Decl/Sema interfaces accept a DeclaratorInfo as parameter but no DeclaratorInfo is created yet.
