Compiler Diff

Yes, I'm still working on it (slowly, though, sorry :( ). Here is a diff of my
current trunk. I don't know what exactly changed since the last version, but
the biggest two things still missing are actually deallocating coarrays in
DEALLOCATE-statements or in types and all the intrinsics like CO_SUM. Locks
already work, though.

Here's an approximate list of features already in the patch (based on the test
cases I have lying around):

- coarray accesses (both implicit `ca` and explicit `ca[1]`)
- this_image/num_images (retrieving image numbers only, no arguments)
- statically allocated arrays
- dynamically allocated arrays
- syncing (SYNC ALL and SYNC IMAGES)
- locking (LOCK_TYPE)
