information for declarations that were referenced via a qualified-id,
e.g., N::C::value. We keep track of the location of the start of the
nested-name-specifier. Note that the difference between
QualifiedDeclRefExpr and DeclRefExpr does have an effect on the
semantics of function calls in two ways:
  1) The use of a qualified-id instead of an unqualified-id suppresses
     argument-dependent lookup
  2) If the name refers to a virtual function, the qualified-id
  version will call the function determined statically while the
  unqualified-id version will call the function determined dynamically
  (by looking up the appropriate function in the vtable).

Neither of these features is implemented yet, but we do print out
qualified names for QualifiedDeclRefExprs as part of the AST printing.

When emitting the static variables we need to make sure that the order is preserved. 
Fix this by making StaticDecls a std::list which has O(1) random removal.

That said, we should probably try and track down the correct clobber 
lists for the targets that don't have them (PPC, ARM, and Sparc), 
so that we can generate correct code.

which can refer to static data members, enumerators, and member
functions as well as to non-static data members.

Implement correct lvalue computation for member references in C++. 
Compute the result type of non-static data members of reference type properly.

simple test that actually does VLA codegen.

Note that despite the fact that the alloca isn't in the entry block, it 
should dominate all uses; this is guaranteed by the restrictions on goto 
into VLA scope in C99.

Check the entire StackSaveValues stack for VLAs when dealing with goto and return statements. Noticed by Eli Friedman.

Emit the size even if the declared type is a variably modified type. This lets us handle

void f(int n) {
  int (*a)[n];
  
  printf("size: %d\n", sizeof(*a));
}

 - Update comment to reflect fact that StructRet is now supported for
   any type (modulo LLVM support).

 - No functionality change, no scalar types currently use this
   feature.

Note that one test duplicate-ivar-check.m will fail because I 
need to re-implement duplicate ivar checking.

Someone should double-check that I didn't somehow break ObjC 
serialization; I think the change there actually changes the semantics.
