to generate virtual method thunks for an available_externally
function.

While collecting members for a class, always create delcaration entry for methods. Debug info for method definition will be generated while generating code for method body. 
Tested by classes.exp in gdb testsuite.

Split the normal and chained PCH writing paths and add a tiny bit of implementation to the latter. WIP.

-O0, since we won't be using the definitions for anything anyway. For
lib/System/Path.o when built in Debug+Asserts mode, this leads to a 4%
improvement in compile time (and suppresses 440 function bodies).

around by exempting enums from the check, but this doesn't handle a lot of
cases. A better approach is to directly check if the operator comes from
a macro expansion.

I've removed a reference to the rdar that originally led to the enum
suppression when removing it's overly contrived test case. Let me know if that
number or a more reasilistic test case involving enums is still needed.

In the case of backtracking, the cached token lexer will be the only 
lexer on the stack, without this the token stack will be empty and EOF
won't be returned.

This fixes PR7072.

root cause of PR7481 and probably more, and has no apparent 
testcases.  I don't understand the logic here so I can't repair it.

a function prototype is followed by a declarator if we
aren't parsing a K&R style identifier list.

Also, avoid skipping randomly after a declaration if a
semicolon is missing.  Before we'd get:

t.c:3:1: error: expected function body after function declarator
void bar();
^

Now we get:

t.c:1:11: error: invalid token after top level declarator
void foo()
          ^
          ;

probably try and switch more of these if I can.

default arguments to template parameters don't have a DeclContext when
instantiated, and so we can't detect that we're in an instantiation context as
opposed to the definition context. However, it fixes the more commonly-occuring
cases in TMP code that use devolve to this type of tautology after
substitution.

When given the -chained-pch option and a previous PCH file, have the PCHWriter emit a CHAINED_METADATA record instead of METADATA, and write a link to the previous file there.

llvm-svn: 108014

for code like this:
   template<template<typename T> class U> class V {};

The problem is that the DeclPrinter assumed all TemplateDecls
have a getTemplatedClass(), but template template params don't
(so we got a NULL dereference).  The solution is to detect if
we're a template template param, and construct the template
class name ('class U') specially in this case.

wrong, and we don't handle floating point value type arguments yet anyways.
Will add correct logic for both when I finish the patch.

as only operating on integral types.

Also, add a FIXME to add support for floating point value types.
