Add a new compiler option. --inform-ite-instead-of-switch. If this is enabled,
the compiler will generate informational messages about if-then-elses that
it thinks should be converted to switches for the sake of program reliability.
Act on the output generated by this option.
compiler/simplify.m:
Implement the new option.
Fix an old bug that could cause us to generate warnings about code
that was OK in one duplicated copy but not in another (where a switch
arm's code is duplicated due to the case being selected for more than
one cons_id).

Convert if-then-elses to switches at most of the sites suggested by the
new option. At the remaining sites, switching to switches would have
nontrivial downsides. This typically happens with the switched-on type
has many functors, and we treat one or two specially (e.g. cons/2 in
the cons_id type).
Perform misc cleanups in the vicinity of the if-then-else to switch
conversions.
In a few cases, improve the error messages generated.
compiler/accumulator.m:
compiler/hlds_goal.m:
(Rename and) move insts for particular kinds of goal from
accumulator.m to hlds_goal.m, to allow them to be used in other
modules. Using these insts allowed us to eliminate some if-then-elses
entirely.
compiler/exprn_aux.m:
Instead of fixing some if-then-elses, delete the predicates containing
them, since they aren't used, and (as pointed out by the new option)
would need considerable other fixing if they were ever needed again.
compiler/lp_rational.m:
Add prefixes to the names of the function symbols on some types,
since without those prefixes, it was hard to figure out what type
the switch corresponding to an old if-then-else was switching on.

Fix an inconsistency between the compiler's handling of foreign_import_module
pragmas (which was itself inconsistent between backends) and what is documented
about that pragma in the reference manual.
According to the reference manual if foreign code (in either a foreign_proc or
foreign_code pragma) wants to refer to pragma foreign_exported procedures from
the same module then there needs to be a foreign_import_module in the module
for itself.
The high-level C backend ignores this entirely and modules always effectively
implicitly foreign import themselves. The situation with the low-level C
backend varies depending on whether a module has any children or not; if it
does then it does not implicitly foreign import itself otherwise it does.
This diff changes the language to require that modules always implicitly
foreign import themselves and adds a workaround to the low-level C backend
to make sure this always happens. (A better fix would be to modify
the frontend of the compiler to handle the implicit foreign imports
for both backends but the lack of structure in the parse tree makes this
quite awkward at the moment.)
Fix a bunch of comments that were out-of-date.
doc/reference_manual.texi:
Change the description of behaviour of
`:- pragma foreign_import_module' so that it matches what the
implementation actually does (well, at least what it actually
does most of the time.) The new behaviour removes the requirement
that modules need to foreign_import themselves. This is pretty much
what users (and implementors) have assumed anyway
compiler/mercury_compile.m:
Make sure that in LLDS grades modules always foreign import themselves
(this was the exception to "most of the time" above.)

Improve the error messages generated for determinism errors involving committed
choice contexts. Previously, we printed a message to the effect that e.g.
a cc pred is called in context that requires all solutions, but we didn't say
*why* the context requires all solutions. We now keep track of all the goals
to the right that could fail, since it is these goals that may reject the first
solution of a committed choice goal.
The motivation for this diff was the fact that I found that locating the
failing goal can be very difficult if the conjunction to the right is
a couple of hundred lines long. This would have been a nontrivial problem,
since (a) unifications involving values of user-defined types are committed
choice goals, and (b) we can expect uses of user-defined types to increase.
compiler/det_analysis.m:
Keep track of goals to the right of the current goal that could fail,
and include them in the error representation if required.

compiler/hlds_data.m:
compiler/prog_data.m:
Move the cons_id type from hlds_data to prog_data, since several parts
of the parse tree data structure depend on it (particularly insts).
Remove the need to import HLDS modules in prog_data.m by making the
cons_ids that refer to procedure ids refer to them via a new type
that contains shrouded pred_ids and proc_ids. Since pred_ids and
proc_ids are abstract types in hlds_data, add predicates to hlds_data
to shroud and unshroud them.
Also move some other types, e.g. mode_id and class_id, from hlds_data
to prog_data.

Move predicates for manipulating cons_ids from hlds_data to prog_util.

Until now, programmers could add `tabled_for_io' annotations to foreign_procs
that do I/O, which asks the compiler to make those foreign_procs idempotent,
i.e. ensures that they are performed at most once even in the presence of a
retry operation in the debugger. This change adds a compiler option,
--trace-table-io-require, which generates an error if a foreign_proc that does
I/O does not have this annotation. Specifying this option thus ensures
that all I/O done by the program is idempotent.
In the future, we may want to have this option turned on in all debugging
grades. Until we decide about, the new option is not yet documented.

Rearrange some code after the `--make' change. This was not done
as part of that change for ease of reviewing.

compiler/make.module_target.m:
compiler/make.program_target.m:
Move code to compile the generated code into compile_target_code.m.

compiler/passes_aux.m:
compiler/process_util.m:
Move process and signal handling functionality into process_util.m.
compiler/Mmakefile:
Compile process_util.c with `--no-ansi' so that the declarations

compiler/notes/compiler_design.html:
Document compile_target_code.m and process_util.m.
Move timestamp.m into the "Miscellaneous" section (it's
used by make as well as smart recompilation).
Fix the documentation of options_file.m.
