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.

% This is a regression test for a limitation of switch detection and
|
|
% common subexpression elimination. The limitation was that when they looked
|
|
% for deconstruction unifications, they stopped looking when encountering
|
|
% a call, even if the call came from the clause head.
|
|
%
|
|
% In the test predicate below, they failed to recognize the common
|
|
% deconstruction of Pair with - and the different deconstructions of List
|
|
% with [] and [ | ], leading determinism analysis to conclude that test may
|
|
% have more than one solution, leading to a bogus determinism error.
