Make these tests use four-space indentation, and ensure that
each module is imported on its own line. (I intend to use the latter
to figure out which subdirectories' tests can be executed in parallel.)
These changes usually move code to different lines. For the tests
that check compiler error messages, expect the new line numbers.

Import only one module per line.

Fix something I missed.
Estimated hours taken: 8
Fix a bug in the module import mechanism -- use_module should
not be transitive. This change is needed for smart recompilation
to avoid needing to check whether the removal of a transitive
import could cause compilation errors -- it never should.
Also fix some bugs in the handling of type class declarations.
compiler/prog_data.m:
Add a `transitively_imported' pseudo-declaration, which
is placed before the items from `.int2' files and `.opt'
files.
Fix the representation of type class bodies.
`:- typeclass foo where [].' declares a typeclass with no
methods. `:- typeclass foo.' declares an abstract typeclass.
The old representation made no distinction between these cases.
compiler/hlds_data.m:
compiler/prog_data.m:
compiler/module_qual.m:
Move the declaration of type type_id from hlds_data.m to prog_data.m.
This avoids a duplicate declaration in module_qual.m.
compiler/modules.m:
Add a `transitively_imported' pseudo-declaration before the
items from `.int2' files.
Remove the bodies of typeclass declarations placed in `.int2'
files -- the methods should not be available unless the module
is explicitly imported.
compiler/module_qual.m:
Items after the `transitively_imported' pseudo-declaration
should not be considered when module qualifying locally
declared items.
compiler/equiv_type.m:
compiler/mercury_to_mercury.m:
compiler/prog_io_typeclass.m:
Handle the change to the representation of typeclass bodies.
compiler/prog_io_typeclass.m:
Check that the arguments of a typeclass declaration
are distinct variables.
compiler/make_hlds.m:
Handle abstract typeclass declarations.
compiler/check_typeclass.m:
Check that all typeclasses have a definition somewhere.
compiler/intermod.m:
Write abstract_exported typeclasses to the `.opt' file.
compiler/add_trail_ops.m:
compiler/context.m:
compiler/llds.m:
compiler/vn_type.m:
Add missing imports.
compiler/magic_util.m:
compiler/ml_type_gen.m:
Remove unnecessary imports.
