Ian Lance Taylor 8cce07d1dd runtime: copy rdebug code from Go 1.7 runtime
While we're at it, update the runtime/debug package, and start running
    its testsuite by default.  I'm not sure why runtime/debug was not
    previously updated to 1.7.  Doing that led me to fix some minor aspects
    of runtime.Stack and the C function runtime/debug.readGCStats.
