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.

browser/tree234_cc.m:
Import only one module per line.
tests/hard_coded/boyer.m:
Fix something I missed.
Branches: main
Fix two compiler aborts in the structure sharing analysis.
compiler/ctgc.selector.m:
Fix a problem with widening structure sharing pairs in the presence of
existential types. We'd try to reduce a term selector to a type
selector of the type of the node selected by the term selector, but if
that node would be existentially typed then the compiler would abort.
To avoid that, we resort to reducing the selector to a type selector of
the parent node's type instead.
Make `type_of_node' and `select_subtype' into semidet predicates which
fail if the selector would select an existentially typed node, rather
than aborting. Add det versions of the original functions.
Make `select_subtype' able to succeed on existentially typed functors
if the selector doesn't actually select an existentally typed
argument.
compiler/structure_sharing.domain.m:
Don't add a new sharing pair to a sharing set if the left and right
hand sides of the sharing pair are the same after normalisation. This
avoids a different abort if such a pair needs to be removed: it tries
to remove both (LHS - RHS) and (RHS - LHS) but since the two sides are
equal, only one copy of the pair would exist in the sharing set to be
removed.
