castxml: Support -std=c++11 with --castxml-gccxml

Parsing standard library headers in Visual Studio 11 and above requires
Clang to use -std=c++11 because the headers use C++11 constructs.  While
gccxml output format does not support these constructs, it is still
useful to be able to output interfaces from C++98 project code while
tolerating C++11 constructs in system headers.

Drop the rejection of -std=c++11 and --castxml-gccxml together.  Teach
our ASTVisitor::AddDumpNode method to skip deleted member functions,
implicit move constructors, and implicit move assignment operators.
This should avoid encountering any C++11 constructs that are not written
explicitly in the translation unit.

Extend the test suite to run all gccxml output format tests in both
-std=c++98 and -std=c++11 mode to verify the behavior of the two modes
is as close as possible.  Tweak the Class-implicit-members expected
output to tolerate the empty throw specification missing in C++11 mode.
Add a RValueReferenceType test to verify that the gccxml-format output
contains an Unimplemented element for the rvalue-reference type.
