Ian Lance Taylor 6748787813 runtime: copy runtime.go and runtime1.go from Go 1.7
Also copy over cputicks.go, env_posix.go, vdso_none.go, stubs2.go, and a
    part of os_linux.go.  Remove the corresponding functions from the C code
    in libgo/go/runtime.  Add some transitional support functions to
    stubs.go.  This converts several minor functions from C to Go.
