this looks good, thanks for taking the time to write it up.  I just
have one question for my own understanding (which may or may not be
relevant to consider for the change):

How does automatic parallelization relate to Graphite?  My understanding 
is that we have automatic parallelization both without Graphite and now 
with Graphite, too, and that -ftree-parallelize-loops= is the general
option and that -floop-parallelize-all comes from Graphite.  If that
is the case, perhaps something like "In addition to -ftree-parallelize-loops=,
specify -floop-parallelize-all to enable the Graphite-based optimization"
or something like that?

(Otherwise there is a blank missing before "need".)
