For very large input files, use of GOSSAFUNC to obtain a dump after compilation steps can lead to both unwieldy large output files and unwieldy larger processes (because the output is buffered in a string). This flag -d=ssa/<phase>/dump:<function name> provides finer control of what is dumped, into a smaller file, and with less memory overhead in the running compiler. The special phase name "build" is added to allow printing of the just-built ssa before any transformations are applied. This was helpful in making sense of the gogo/protobuf problems. The output format was tweaked to remove gratuitous spaces, and a crude -d=ssa/help help text was added.
