Weird code sometimes uses pointer constants other than null. This patch
teaches SimplifyCFG to build switch instructions in those cases.

Code like this:

void f(const char *x) {
  if (!x)
    puts("null");
  else if ((uintptr_t)x == 1)
    puts("one");
  else if (x == (char*)2 || x == (char*)3)
    puts("two");
  else if ((intptr_t)x == 4)
    puts("four");
  else
    puts(x);
}

Now becomes a switch:

define void @f(i8* %x) nounwind ssp {
entry:
  %magicptr23 = ptrtoint i8* %x to i64            ; <i64> [#uses=1]
  switch i64 %magicptr23, label %if.else16 [
    i64 0, label %if.then
    i64 1, label %if.then2
    i64 2, label %if.then9
    i64 3, label %if.then9
    i64 4, label %if.then14
  ]

Note that LLVM's own DenseMap uses magic pointers.

follows (as conservatively as possible) gcc's current behavior:  attributes
written on return types that don't apply there are applied to the function
instead, etc.  Only parse CC attributes as type attributes, not as decl attributes;
don't accepet noreturn as a decl attribute on ValueDecls, either (it still
needs to apply to other decls, like blocks).  Consistently consume CC/noreturn
information throughout codegen;  enforce this by removing their default values
in CodeGenTypes::getFunctionInfo().

when instantiating the declaration of a member template:
  - Only check if the have a template template argument at a specific position
  when we already know that we have template arguments at that level;
  otherwise, we're substituting for a level-reduced template template
  parameter. 
  - When trying to find an instantiated declaration for a template
  template parameter, look into the instantiated scope. This was a
  typo, where we had two checks for TemplateTypeParmDecl, one of
  which should have been a TemplateTemplateParmDecl.

With these changes, tramp3d-v4 passes -fsyntax-only.
