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.

Fix a bug (#27) reported by Ralph. The compiler was aborting on
instances that contained type variables that were not wrapped in functors.
The problem is that the name mangling scheme used to mangle the names of
method wrapper predicates cannot handle instances that contain unwrapped
type variables. The compiler already has code to check for this, but that
check was not being performed until *after* it had attempted to introduce
the method wrapper predicates.
The fix is to reorder the phases of check_typeclass.m so that we perform
the check on the types in an instance first and only run the remaining
phases if the first one succeeds.
compiler/check_typeclass.m:
Reorder the phases within this module so that we don't attempt
to introduce method wrapper predicates for invalid instances.
Update the documentation in this module to conform to the above
change.
Remove some unnecessary module qualification.

tests/invalid/instance_var_bug.{m,err_exp}:
Test for the above bug.
tests/invalid/bad_instance.err_exp:
Update this. The error message for the missing concrete instance
won't be emitted with the above change. Note, we have a separate
test case, tests/invalid/missing_concrete_instance, that exercises
that error message.
