This allows more concise syntax when allocating an object using the ASTContext's allocator.
Convert a few allocations to this operator to for test purposes.

 - This is a hack to allow the Darwin linker to get -final_output when
   doing universal builds; the mechanism should be generalized.

 - Handle multiple redundant -arch arguments correctly.

 - Forward -arch_multiple and -final_output to gcc when necessary.

 - Simplified implementation of derived gcc tools.

When using a BumpPtrAllocator, this reduces malloc overhead from 2.2->1.9% (for Cocoa.h).

At this point, malloc() has dropped the fourth most expensive routine (behind Preprocessor::HandleIdentifier()).

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.

va_list is a struct, like x86-64.

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.

 - Add Darwin_X86_CC1Tool which is shared by Darwin/x86/Compile and
   Darwin/x86/Preprocess tools.

PTH: Emitted tokens now consist of 12 bytes that are loaded used 3 32-bit loads.  This reduces user time but increases system time because of the slightly larger PTH file.  Although there is no performance win on Cocoa.h and -Eonly, overall this seems like a good step.
