[www] Remove implemented Open Project

[kbobyrev]

Summary

"Open LLVM Projects" page is used by students willing to apply for Google Summer of Code, this patch updates the page by removing the "Reimplement LLDB's command-line commands using the public SB API" project implemented during GSoC 2018.

@aprantl if there is still some work left for GSoC/potential contributors, feel free to mention it and then it should be just updated for the future. I couldn't infer whether there is still a chunk of work to be done from the project report, but you might have more information.

Thanks, LGTM!

   <p><b>Description of the project: </b>
-    The C++ std::string class provides a c_str() method that returns a raw pointer to a string's inner character buffer. When a std::string is destroyed, the character buffer is deallocated. A common bug is to access a dangling raw pointer to the buffer after string deallocation. These "use after free" bugs can cause crashes or other unexpected behavior.

     <br />
     This project will add a new checker to the static analyzer to find when a dangling inner string pointer is used. This will help find bugs not only with std::string and c_str() but also with LLVM's StringRef class and the new C++17 std::string_view.

   <p><b>Description of the project: </b>
     The static analyzer finds bugs by exploring many possible paths through a program. To reduce false positives, it uses a very fast but imprecise custom constraint manager to rule out infeasible paths that cannot actually be executed at run time.

+    <br />
     This project will extend the analyzer to use the <a href="https://github.com/Z3Prover/z3/wiki">Z3 SMT solver</a> to rule out additional infeasible paths by postprocessing bug reports. This will help the analyzer reduce false positives when the path involves complicated branches that the built-in constraint manager cannot reason about.
