d: Split up the grouped compilable and runnable tests.

The majority of tests in runnable are really compilable/ICE tests, and
have have dg-do adjusted where necessary.  Tests that had a dependency
on Phobos have also been reproduced and reduced with all imports
stripped from the test.

The end result is a collection of tests that only check the compiler bug
that was being fixed, rather than the library, and a reduction in time
spent running all tests.
