Summary: This aims to replace the different decorators we've had on each libc++ test with a single solution. Each libc++ will be assigned to the "libc++" category and a single central piece of code will decide whether we are actually able to run libc++ test in the given configuration by enabling or disabling the category (while giving the user the opportunity to override this). I started this effort because I wanted to get libc++ tests running on android, and none of the existing decorators worked for this use case: - skipIfGcc - incorrect, we can build libc++ executables on android with gcc (in fact, after this, we can now do it on linux as well) - lldbutil.skip_if_library_missing - this checks whether libc++.so is loaded in the proces, which fails in case of a statically linked libc++ (this makes copying executables to the remote target easier to manage). To make this work I needed to split out the pseudo_barrier code from the force-included file, as libc++'s atomic does not play well with gcc on linux, and this made every test fail, even though we need the code only in the threading tests. So far, I am only annotating one of the tests with this category. If this does not break anything, I'll proceed to update the rest.
