We need to be able to locate `swift-backtrace` relative to the current location of the runtime library. This needs to work: * In a Swift build directory. * On Darwin, where we're installed in /usr/lib/swift and /usr/libexec/swift. * On Linux, where we're in /usr/lib/swift/linux and /usr/libexec/swift/linux. * On Windows, where we may be in a flat directory layout (because of limitations of Windows DLL lookups). rdar://103071801
