Cleanup some processing with DeclStmt, and gradually start using the internal BumpPtrAllocator to allocator more of CFG's data structures.

When serializing DeclStmt, encode a bit indicating whether or not the DeclStmt owns the Decl.  This is an interim solution.

llvm-svn: 54410

llvm-svn: 54381

Added decl_iterator to DeclStmt to provide an abstract interface to iterate over the ScopedDecls of a DeclStmt.
Updated a few clients of DeclStmt::getNextDeclarator() to use decl_iterator instead.  Will update other clients after additional testing.

Finally fix PR2189.  This makes a fairly invasive but important change to
move getAsArrayType into ASTContext instead of being a method on type.
This is required because getAsArrayType(const AT), where AT is a typedef
for "int[10]" needs to return ArrayType(const int, 10).

Fixing this greatly simplifies getArrayDecayedType, which is a good sign.

Fix serialization for TypedefType by allowing TypedefType to access the internal CanonicalType stored in Type.
The test case Serialization/stmt_exprs.c now passes.

Serialization/stmt_exprs.c, but I don't know the right solution.  Will fix
when I get a chance to talk to Ted about it.

ASTContext::getCanonicalType instead (PR2189)

improve 'expression unused' diagnostics for stmtexprs.

First, fix canonical type handling of these, since protocol qualified id's are always
canonical.  Next, enhance SemaType to actually make these when used (instead of int)
allowing them to actually be used when appropriate.  Finally remove a bunch of logic
relating to the mishandling of canonical types with protocol-qual id's.  This fixes

When constructing an ObjCIvarDecl object in Sema, provide its visibility up front instead of setting it afterwards.
This change also fixes a subtle bug where the access control of an ivar would be initialized to garbage if we didn't have an explicit visibility specifier (e.g., @private).

simplifying code along the way and fixing a problem and memory leak or two.

various objc lists over to it.  First up, the protocol list 
on ObjCInterfaceDecl.

llvm-svn: 53856

be consistent with ObjCInterfaceDecl.

llvm-svn: 53852

the standard "set these as the list of protocols" interface instead of a 
strange "set this as the size and then set each one to the value" interface.
The problem with the later is that it a) is completely different from 
everything else, b) is awkward, and c) doesn't handle the case when a
referenced protocol is invalid: it set it to null.

This meant that all clients downstream would have to handle null protocols
in the protocol list, and empirically they didn't.  Fix this by not setting
invalid protocols in the referenced protocol list, fixing the crash on 
test/Sema/objc-interface-1.m

While I'm at it, clean up some locations so that we produce:

t.m:1:25: error: cannot find interface declaration for 'NSObject', superclass of 'NSWhatever'
@interface NSWhatever : NSObject <NSCopying>
~~~~~~~~~~~~~~~~~~~~~   ^

instead of:

t.m:1:1: error: cannot find interface declaration for 'NSObject', superclass of 'NSWhatever'
@interface NSWhatever : NSObject <NSCopying>
^

- Make sure ObjCIvarDecl propagates the bitfield width.
- RewriteObjC::SynthesizeIvarOffsetComputation(): Avoid using the __OFFSETOF__ mumbo jumbo for bitfields (since it isn't legal C). This fixes <rdar://problem/5986079> clang ObjC rewriter: bitfields and ivar access don't mix.
