Finishing touches on code generation for @try and friends.

- declare functions we use.
- cast arguments to objc_exception_match().
- don't take the & of _stack.buf.

Remove old asserts from ASTContext::isObjcIdType() and isObjcClassType(). Instead, return false if the declarations aren't in scope. This was a hold over from when 'id' and 'Class' were initialized lazily.

Added "FIXME" regarding the lack of source location information for IndirectGotoStmt.

Fixed declarations of several "directEmit" methods of classes that subclass
Stmt that were missing a "virtual" keyword.

Teach ASTContext::tagTypesAreCompatible() about the built-in ObjC types (Class and id), removing a bogus warning.

llvm-svn: 43809

and ParenExpr.

Rewrite ObjC @try/@catch/@finally. Some minor tweaks to the AST nodes...

Still need to rewrite @throw (and do more testing)...

Reordered stmt serialization method implementations to be in alphabetical order.

is not yet complete.

serialize Type objects in the order they are serialized in the Types
vector.  We also now rely on the methods within ASTContext to unique
Type objects and handle the actual creation of Type objects (these are
now called by the deserialization code).  This approach solves some
hairy issues with ownership of objects and allows us to naturally
handle recursive types.

for ASTContext is still rapidly evolving.

llvm-svn: 43774

Revampled Serialization Tester to serialize and deserialize out an entire ASTContext and top-level decls.

llvm-svn: 43773

Fix a "basic" bug that resulted in a bogus SourceLocation.

Off hand, I don't know why this change makes a difference (I thought the two constructor idioms were equivalent).

Fixed infinite recursion in VarDecl::InternalRead.
