Add __has_feature and __has_extension checks for C++1y features (based on the provisional names from
the C++ features study group), and update documentation to match.

These are two related changes (one in llvm, one in clang).
LLVM:
- rename address_safety => sanitize_address (the enum value is the same, so we preserve binary compatibility with old bitcode)
- rename thread_safety => sanitize_thread
- rename no_uninitialized_checks -> sanitize_memory
CLANG:
- add __attribute__((no_sanitize_address)) as a synonym for __attribute__((no_address_safety_analysis))
- add __attribute__((no_sanitize_thread))
- add __attribute__((no_sanitize_memory))
for S in address thread memory
If -fsanitize=S is present and __attribute__((no_sanitize_S)) is not
set llvm attribute sanitize_S

Language extensions are highly relevant to using clang as a compiler, so
move LanguageExtensions up into `Using Clang as a Compiler` on the
landing page.
The other documents from the now-gone `Language Extensions and Specs`
section on the landing page nicely fit hierarchically under
LanguageExtensions.rst, so put them under LanguageExtensions.rst's
toctree instead of on the landing page.
Impetus from Jordan Rose.

The notes on the objc_method_family and ns_returns_retained-type attributes
have been moved to the Objective-C section, since both are used by ARC.
The notes on analyzer_noreturn are now only on the analyzer site.
The inadequacy of these docs was noticed months ago by Jonathan Sauer;
I'm only just now getting around to cleaning them up.
