      cmd/gc: racewalk: fix compiler crash · ca4b868e
      Dmitriy Vyukov authored 
      The code:
func main() {
        v := make([]int64, 10)
        i := 1
        _ = v[(i*4)/3]
}
crashes compiler with:

Program received signal SIGSEGV, Segmentation fault.

The problem is nil init passed to mkcall().

      runtime: struct Obj in mgc0.c and buffers in scanblock() · 013fa63c
      Jan Ziak authored 
      Details:

- This CL is the conceptual skeleton of code found in CL 6114046

- The garbage collector uses struct Obj to specify memory blocks

- scanblock() is putting found memory blocks into an intermediate buffer
  (xbuf) before adding/flushing them to the main work buffer (wbuf)

- The main loop in scanblock() is replaced with a skeleton code that
  in the future will be able to recognize the type of objects and
  thus will improve the garbage collector's precision.
  For now, all objects are simply sequences of pointers so
  the precision of the garbage collector remains unchanged.

- The code plugs .gcdata and .gcbss sections into the garbage collector.
  scanblock() in this CL is unable to make any use of this.
