We now only raise the magic exception that names the thread when IsDebuggerPresent() returns true. In such a case, Visual Studio will catch the exception, set the thread name, and let the debugged process continue normally. If the debugger isn't running, we don't raise an exception at all. Setting the name is a debugger trick; if the debugger isn't running, the name won't be set if attached later in any case, so this doesn't lose functionality. This lets this code work without assembly code, on win32 and win64, and across various compilers. The only "gotcha" is that if you have something attached that looks like a debugger but doesn't respect this magic exception trick, the process will likely crash, but that's probably a deficiency of the attached program. Fixes Bugzilla #2089.
