Port all remaining regression tests to lit

We have re-classified a subset of the regression tests as unit tests and
now we are porting the remaining ones.

Test discovery and running is now performed by lit rather than ctest.
The tests continue to use their original scripts with minor
modifications. Most of the changes were mechanical and so scripted.
A few changes were made by hand. Details

Manual:
  * modfile09-*.f90 tests depend on being run together as some tests have
    dependencies on modules created by other tests. This will need
     separating out when porting away from test_modfile.sh, but for now,
     added modfile09-*.f90 to the Inputs directory and added a single
     tests modfile09.f90 to hold the run line.
  * getdefinition03-a.f90 includes a non-test file getdefinition03-b.f90.
    Manually edited the former to find the latter in Inputs so as to add
    only one test.
  * Same pattern for getsymbols03-{a,b}.f90

Auto:
  * Remaining tests have a lit RUN line added to them based on the type
    of test they are.
  * Failing tests also have an XFAIL line added to them.
  * Generic tests have their pre-existing RUN lines replaced with the
    word "EXEC" to avoid conflict with the added lit RUN line.
