tests/warnings/*.m:
Bring the programming style of these modules up to date,
except where the problem being tested for seems to be related
to the old programming style
In the infinite_recursion test case, add code that we *should*
warn about, but currently don't.
tests/warnings/*.m:
Update the expected outputs to account for the changes in line
numbers, and the fact that the compiler computes the contexts
of (if C then T else E) if-then-elses differently from (C -> T; E)
if-then-else (it takes the context of the "then" vs the context
of the ";").
Delete arg_order_rearrangment.exp2. It was long unused, but
deleting it in CVS would not have allowed us to put it back later.
This fixes Mantis bug #412.
compiler/unused_imports.m:
Consider that an instance declaration makes a module "used" only if
it occurs in the module being compiled, not in an imported or ancestor
module. (Mantis bug 412 was caused by instance declarations in implicitly
imported modules.)
Fixing #412 also exposed another bug. When computing the set of modules
used by predicates, we considered (besides some non-type entities)
only the types of the predicate's arguments, not the types of non-argument
variables. In one case in the compiler (mmc_analysis.m), this lead to
some actually-used modules not being marked as such, which lead to
false unused-import warnings to be generated for them. Fix this by scanning
the types of all variables in all of a predicate's procedures, not just
the arguments.
Improve the infrastructure for debugging similar problems.
Note some possibilities for future improvement.
Change a predicate name to fit the naming scheme.
compiler/analysis.m:
Add an XXX about a possible improvement.
compiler/hlds_out_module.m:
Make the output we generate for instance methods more readable.
As part of this, fix an old bug in the printing of the instance table:
the first line of the first method of each concrete instance declaration
was accidentally commented out.
compiler/parse_tree_out.m:
Export a different utility predicate for hlds_out_module.m. Make its name
conform to the scheme used by related predicates.

The test case for this bug.
tests/warnings/Mmakefile:
tests/warnings/Mercury.options:
Enable the new test case.
tests/invalid/import_in_parent.err_exp:
Update the expected output for this test case. The parent module
does not use the imported module (bool) at all, so this is what the
error message says after this diff, though its submodule does use bool.
