Sink the Db initialization into the structure rather than out-of-line at the
declaration size. This just makes it easier to see what initialization is being
performed. NFC.

The block invocation function uses an extension where the prefix is ___Z
as opposed to _Z. This should make the tests pass again.
Disable a negative test which was testing a crasher. The symbol being
demangled is not a valid mangled symbol and will return a nullptr.
Adjust the type info decoding test to be a valid symbol name.

Ensure that we have a mangled symbol before attempting to demangle it. We would
previously treat any input as a mangled symbol rather than checking that the
symbol has the initial C++ Itanium v3 mangling prefix of `_Z`. This changes the
behaviour from the previous case which would undecorate `f` to `float` rather
than nullptr as it should.
Unfortunately, we do not have any negative testing for the demangler.

Mark functions and types with the appropriate visibility. This is particularly
useful for environments which explicitly indicate origin of functions (Windows).
This aids in generating libc++abi as a DSO which exposes only the public
interfaces.

libstdc++ needs a few typedefs in malloc_alloc. MSVC's STL needs rebind(),
construct(), destroy(). MSVC2013 also has no snprintf, but it exists in 2015.

Summary:
Patch by Nitesh Jain and Jaydeep Patil with a small revision to use ABIs rather
than Architecture Revisions (which currently imply particular ABIs).
Fixes test_demangle.pass.cpp (PR24149).

The externC variable was set but unused. This constantly flagged a warning from
gcc. Replace it with a comment until such a time that we need it.

Cleans up the -Wundef warning caused by the use of the __LITTLE_ENDIAN__ macro.
Instead use `__BYTE_ORDER__ == __ORDER_LITTLE_ENDIAN__`. `__BYTE_ORDER__` is
defined by GCC since 4.2 and by clang. This avoids the undef case where a macro
may be undefined. This has previously caught real errors in libunwind.

There is some debugging code in cxa_demangle.cpp that prints messages on
stdout. In general this is not safe, as the program itself may use
stdout to write its output. Change this code to write to stderr.

- GCC doesn't support #pragma mark, only Apple GCC and clang. Wrap the pragma mark's in #if 0 to make gcc ignore them but xcode still see them.
- Wrap a bunch of "#pragma clang" lines in #ifdef __clang__.
- Pacify gcc's -Wparenthesis in a case where it's quite reasonable.

There was a single problem in cxa_demangle.cpp, where gcc would complain
`error: changes meaning of 'String'` about the line `typedef String String;`.
According to 3.3.7p2, this diagnostic is allowed (but not required, so clang
does not have to report this).
As a fix, make string_pair a template and pass String as template parameter.
This fixes the error with gcc and also removes some repetition from the code.
No behavior change.

determine whether we get a mangling for a return type, rather than trying to
figure it out based on whether the mangled name ended with a '>'.

substitution forward references. That is, sometimes a mangled name refers to
a substitution that hasn't yet been defined. The demangler was derferencing a
null pointer in this case because it wasn't properly guarded against a
forward reference. Test case added to catch this problem.
