New wiki page for openmp and parallelization

[Diego Novillo]

I've created a new wiki page to track things we'd like to add/fix/remove 
to the OpenMP implementation and related things like the auto 
parallelizer (http://gcc.gnu.org/wiki/openmp)

I've linked the page to the Google SoC projects wiki page.  If you have 
anything that you'd been wanting to work on, feel free to add it to the 
list.


Thanks.  Diego.
