Look at incomplete FunctionTemplateDecls in order to determine whether
a CXXRecordDecl is complete. Fixes Bug 13086.

Still more Doxygen documentation fixes:
* Escape #, < and @ symbols where Doxygen would try to interpret them;
* Fix several function param documentation where names had got out of sync;
* Delete param documentation referring to parameters that no longer exist.

Fix PR13065.

This condition (added in r158093) was overly conservative.

Ongoing documentation cleanup: fixed Doxygen markup errors, added \brief
annotations in many places where it involved little change, fixed some
examples and marked code examples with \code...\endcode, and changed a few
nearby mentions of C++0x to refer to C++11.

PR12717: Clang supports hexadecimal floating-point literals in all language
modes. For languages other than C99/C11, this isn't quite a conforming
extension, and for C++11, it breaks some reasonable code containing
user-defined literals.

In languages which don't officially have hexfloats, pare back this extension
to only apply in cases where the token starts 0x and does not contain an
underscore. The extension is still not quite conforming, but it's a lot closer
now.

It turns out that implementing the rethrow-on-fallthrough
semantics of a ctor/dtor function-try-block catch handler
by pushing a normal cleanup is not just overkill but actually
actively wrong when the handler contains an explicit return
(which is only legal in a dtor).  Just emit the rethrow as
ordinary code at the fallthrough point.  Fixes PR13102.
