Fixes a bug that surfaces in frame recognizers. Details about the bug: A new frame recognizer is configured to match a specific symbol (`swift_willThrow`). This is an `extern "C"` symbol defined in a C++ source file. When Swift is built with debug info, the function `ParseFunctionFromDWARF` will use the debug info to construct a function name that looks like a C++ declaration (`::swift_willThrow(void *, SwiftError**)`). The `Mangled` instance will have this string as its `m_demangled` field, and have _no_ string for its `m_mangled` field. The result is the frame recognizer would not match the symbol to the name (`swift_willThrow` != `::swift_willThrow(void *, SwiftError**)`. By changing `ParseFunctionFromDWARF` to assign both a demangled name and a mangled, frame recognizers can successfully match symbols in this configuration.
