Don't require a space between the two ">" in "vector<id<protocol>>" in objc++11.

C++11 allowed writing "vector<vector<int>>" without a space between the two ">".
This change allows this for protocols in template lists too in -std=c++11 mode,
and improves the diagnostic in c++98 mode.

Don't hit an assertion failure when calculating the __PRETTY_FUNCTION__
of a member function with parenthesized declarator.

Like this test case:

class Foo {
  const char *(baz)() {
    return __PRETTY_FUNCTION__;
  }
};

Remove old description of analyzer internals from public docs.

The file still exists in docs/analyzer/, but it won't be linked to from
clang.llvm.org or processed as part of the default Sphinx doc-build.
RegionStore has changed a lot from what Ted and Zhongxing describe here!

Docs: redirect "static analysis extensions" section to the analyzer site.

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.

Results in better block placement that helps close the
