For Thread Sanitizer reports, LLDB tries to find a global variable declaration corresponding to the racy address in order to provide a filename and line number. This commit changes the lookup of the variable to use the mangled name for lookup and fall back to the demangled version if unavailable. This is needed to report locations of races on Swift global variables.

I've also added a test to make sure we look up C++ globals correctly.
