declarations of same, introduce a single AST class and add appropriate bits
(encoded in the namespace) for whether a decl is "real" or not. Much hackery
about previously-declared / not-previously-declared, but it's essentially

fairly non-intrusive.
Refactor the Sema methods specific to friends for cleaner flow and less nesting.
Incidentally solve a few bugs, but I remain confident that we can put them back.

accurately. Prevents the assert from triggering incorrectly when friending
functions first declared in extern "C" contexts. Fixes bug 4757.

Permit a class to friend its class members in C++ 98, as long as extensions
are enabled (and even when they aren't, only give an extwarn about it).

Doug, please look at decltype-crash and instantiate-function-1.mm, I'm not sure
if they are actually testing the right thing / anything.
