[libc++] Fix ssize test that made an assumption about ptrdiff_t being 'long'

On some platforms like armv7m, the size() method of containers returns
unsigned long, while ptrdiff_t is just int. Hence, std::ssize_t ends up
being long, which is not the same as ptrdiff_t. This is usually not an
issue because std::ptrdiff_t is long, so everything works out, but it
breaks on some more exotic architectures.

[libc++] NFC: Fix several GCC warnings in the test suite

- Several -Wshadow warnings
- Several places where we did not initialize our base class explicitly
- Unused variable warnings
- Some tautological comparisons
- Some places where we'd pass null arguments to functions expecting
non-null (in unevaluated contexts)
- Add a few pragmas to turn off spurious warnings
- Fix warnings about declarations that don't declare anything
- Properly disable deprecation warnings in ext/ tests (the pragmas we
were using didn't work on GCC)
- Disable include_as_c.sh.cpp because GCC complains about C++ flags
when compiling as C. I couldn't find a way to fix this one properly,
so I'm disabling the test. This isn't great, but at least we'll be
able to enable warnings in the whole test suite with GCC.

[libc++] Remove the c++98 Lit feature from the test suite

C++98 and C++03 are effectively aliases as far as Clang is concerned.
As such, allowing both std=c++98 and std=c++03 as Lit parameters is
just slightly confusing, but provides no value. It's similar to allowing
both std=c++17 and std=c++1z, which we don't do.

This was discovered because we had an internal bot that ran the test
suite under both c++98 AND c++03 -- one of which is redundant.
