Douglas Gregor 56d5f0abaa Add __has_feature(cxx_reference_qualified_functions); update tests and
documentation.

Douglas Gregor c41d94eb1a Clean up the C++0x __has_feature tests. Specifically:
- Don't publicize a C++0x feature through __has_feature if we aren't
    in C++0x mode (even if the feature is available only with a
    warning). 
  - "auto" is not implemented well enough for its __has_feature to be
    turned on.
  - Fix the test of C++0x __has_feature to actually test what we're
  trying to test. Searching for the substring "foo" when our options
  are "foo" and "no_foo" doesn't work :)

Douglas Gregor 0098499f7d Downgrade the error about rvalue references to an extension warning
and turn on __has_feature(cxx_rvalue_references). The core rvalue
references proposal seems to be fully implemented now, pending lots
more testing.

Douglas Gregor eecc6bc388 Variadic templates are fully implemented.
Turn on the __has_feature switch for variadic templates, document
their completion, and put the ExtWarn into the c++0x-extensions
warning group.

Argyrios Kyrtzidis 1cb0de1d4c Fix diagnostic pragmas.
Diagnostic pragmas are broken because we don't keep track of the diagnostic state changes and we only check the current/latest state.
Problems manifest if a diagnostic is emitted for a source line that has different diagnostic state than the current state; this can affect
a lot of places, like C++ inline methods, template instantiations, the lexer, etc.

Fix the issue by having the Diagnostic object keep track of the source location of the pragmas so that it is able to know what is the diagnostic state at any given source location.

Fixes rdar://8365684.

Argyrios Kyrtzidis de2bdf637e Revert r119838 "Don't warn for empty 'if' body if there is a macro that expands to nothing"
and use a better and more general approach, where NullStmt has a flag to indicate whether it was preceded by an empty macro.

Thanks to Abramo Bagnara for the hint!

Argyrios Kyrtzidis 90ee2a4ecf Don't warn for empty 'if' body if there is a macro that expands to nothing, e.g:
if (condition)
    CALL(0); // empty macro but don't warn for empty body.

Fixes rdar://8436021.

Douglas Gregor 453b012513 Make sure to always check the result of
SourceManager::getPresumedLoc(), so that we don't try to make use of
an invalid presumed location. Doing so can cause crashes.

Douglas Gregor 5ef9e33137 Make the deserialization of macro definitions lazy, so that we can
load identifiers without loading their corresponding macro
definitions. This is likely to improve PCH performance slightly, and
reduces deserialization stack depth considerably when using
preprocessor metaprogramming.

Douglas Gregor 796d76a663 Extend the preprocessing record and libclang with support for
inclusion directives, keeping track of every #include, #import,
etc. in the translation unit. We keep track of the source location and
kind of the inclusion, how the file name was spelled, and the
underlying file to which the inclusion resolved.

Chris Lattner b6f77af532 implement and document a new __has_feature and __has_builtin magic
builtin preprocessor macro.  This appears to work with two caveats:
1) builtins are registered in -E mode, and 2) target-specific builtins
are unconditionally registered even if they aren't supported by the
target (e.g. SSE4 builtin when only SSE1 is enabled).
