Add debug hook to DeclContext.

llvm-svn: 62605

function DeclaratorChunk in common cases.  This uses a fixed array in 
Declarator when it is small enough for the first function declarator chunk
in a declarator.

This eliminates all malloc/free traffic from DeclaratorChunk::getFunction
when running on Cocoa.h except for five functions: signal/bsd_signal/sigset,
which have multiple Function DeclChunk's, and 
CFUUIDCreateWithBytes/CFUUIDGetConstantUUIDWithBytes, which take more than
16 arguments.

This patch was pair programmed with Steve.

Rename DeclContext::insert to DeclContext::makeDeclVisibleInContext and document both it and DeclContext::addDecl properly

Remove the TopLevelDecls from TranslationUnit, since all of those decls are owned by the ASTContext's TranslationUnitDecl. There are definitely some leaking Decls now that I'll tackle tomorrow

that every declaration lives inside a DeclContext.

Moved several things that don't have names but were ScopedDecls (and,
therefore, NamedDecls) to inherit from Decl rather than NamedDecl,
including ObjCImplementationDecl and LinkageSpecDecl. Now, we don't
store empty DeclarationNames for these things, nor do we try to insert
them into DeclContext's lookup structure.

The serialization tests are temporarily disabled. We'll re-enable them
once we've sorted out the remaining ownership/serialiazation issues
between DeclContexts and TranslationUnion, DeclGroups, etc.

new DiagnoseIncompleteType. It provides additional information about
struct/class/union/enum types when possible, either by pointing to the
forward declaration of that type or by pointing to the definition (if
we're in the process of defining that type).

even when we are still defining the TagDecl. This is required so that
qualified name lookup of a class name within its definition works (see
the new bits in test/SemaCXX/qualified-id-lookup.cpp).

As part of this, move the nested redefinition checking code into
ActOnTag. This gives us diagnostics earlier (when we try to perform
the nested redefinition, rather than when we try to complete the 2nd
definition) and removes some code duplication.

analysis and AST-building for the cases where we have N != 1
arguments. For N == 1 arguments, we need to finish the C++
implementation of explicit type casts (C++ [expr.cast]).

Use a single function for doing vararg argument promotion. Also, make sure to do the promotion before checking the type - fixes PR3340.

Slightly speed up sema of numbers like '1' by going directly to 
TargetInfo instead of through ASTContext.
