<rdar://problem/10944309> CrashTracer: [USER] 111 crashes in WebProcess at WebKitTestRunnerInjectedBundle: WTR::InjectedBundle::done + 142
Fix crash preventing WebKitTestRunner from working in Release.  
WebKitTestRunner used ostringstream to collect output from the test.  ostringstream is incompatible with our
FastMalloc overrides.  When copying strings out ostringstream a new string is allocated with FastMalloc because
the allocation is inlined.  When that string is freed is uses the system malloc because that call is not inlined.

I removed ostringstream in favor of StringBuilder.  

Properly set NDEBUG on Release builds so we don't crash when when we free the strings StringBuilder created.

Add DEBUG_DEFINES to set NDEBUG on release builds.
