Keith Randall c526f3ac10 runtime: tail call into memeq/cmp body implementations
There's no need to call/ret to the body implementation.
It can write the result to the right place.  Just jump to
it and have it return to our caller.

Old:
  call body implementation
  compute result
  put result in a register
  return
  write register to result location
  return

New:
  load address of result location into a register
  jump to body implementation
  compute result
  write result to passed-in address
  return

It's a bit tricky on 386 because there is no free register
with which to pass the result location.  Free up a register
by keeping around blen-alen instead of both alen and blen.

Binary Distribution Notes

If you have just untarred a binary Go distribution, you need to set the environment variable $GOROOT to the full path of the go directory (the one containing this file). You can omit the variable if you unpack it into /usr/local/go, or if you rebuild from sources by running all.bash (see doc/install-source.html). You should also add the Go binary directory $GOROOT/bin to your shell's path.

For example, if you extracted the tar file into $HOME/go, you might put the following in your .profile:

export GOROOT=$HOME/go
export PATH=$PATH:$GOROOT/bin

See https://golang.org/doc/install or doc/install.html for more details.
