do we really have to merge this? Why does it have to be in toplev.c
and using global variables?
What do you think to not commit all this stuff at all, and leave all
this stuff in the Graphite branch for the moment?
Frankly, I don't think that the read/write interface should be exposed
to programmers. I used these options once to test some loop
transforms by hand: it was useful and quite simple to use, but I never
used these flags after that.
The read/write flags may be useful to the http://ctuning.org folks,
but they could come up with a better way to interact with Graphite.
