This object controls when the warnings are executed, allowing the client code
in Sema to selectively disable warnings as needed.

Centralizing the logic for analysis-based warnings allows us to optimize
when and how they are run.

Along the way, remove the redundant logic for the 'check fall-through' warning
for blocks; now the same logic is used for both blocks and functions.

shadowing it in the GlobalDeclMap.  Eliminates the string-uniquing
requirement for mangled names, which should help C++ codegen times a little.
Forces us to do string lookups instead of pointer lookups, which might hurt
codegen times a little across the board.  We'll see how it plays out.

Removing the string-uniquing requirement implicitly fixes any bugs like
PR6635 which arose from the fact that we had multiple uniquing tables for
different kinds of identifiers.

record (which includes all macro instantiations and definitions). As
with all lay deserialization, this introduces a new external source
(here, an external preprocessing record source) that loads all of the
preprocessed entities prior to iterating over the entities.

The preprocessing record is an optional part of the precompiled header
that is disabled by default (enabled with
-detailed-preprocessing-record). When the preprocessor given to the
PCH writer has a preprocessing record, that record is written into the
PCH file. When the PCH reader is given a PCH file that contains a
preprocessing record, it will be lazily loaded (which, effectively,
implicitly adds -detailed-preprocessing-record). This is the first
case where we have sections of the precompiled header that are
added/removed based on a compilation flag, which is
unfortunate. However, this data consumes ~550k in the PCH file for
Cocoa.h (out of ~9.9MB), and there is a non-trivial cost to gathering
this detailed preprocessing information, so it's too expensive to turn
on by default. In the future, we should investigate a better encoding
of this information.

entity (if applicable) which was actually looked up.  If a candidate was found
via a using declaration, this is the UsingShadowDecl;  otherwise, if
the candidate is template specialization, this is the template;  otherwise,
this is the function.

The point of this exercise is that "found declarations" are the entities
we do access control for, not their underlying declarations.  Broadly speaking,
this patch fixes access control for using declarations.

There is a *lot* of redundant code calling into the overload-resolution APIs;
we really ought to clean that up.

deserialization of precompiled headers, where the deserialization of
the source location entry for a buffer (e.g., macro instantiation
scratch space) would overwrite a one-element FileID cache in the
source manager. When tickled at the wrong time, we would return the
wrong decomposed source location and eventually cause c-index-test to
crash.

Found by dumb luck. It's amazing this hasn't shown up before.

access to the (elevated) access of the accessed declaration, if applicable,
rather than plunking that access onto the end after we've calculated the
inheritance access.

Also, being a friend of a derived class gives you public access to its
members (subject to later modification by further inheritance);  it does
not simply ignore a single location of restricted inheritance.

Also, when computing the best unprivileged path to a subobject, preserve
the information that the worst path might be AS_none (forbidden) rather
than a minimum of AS_private.
