tests/hard_coded/*.m:
Rename modules as mentioned above.
In a few cases, where the main module's name itself had a suffix,
such as "_mod_a" or "_main", remove that suffix. This entails
renaming the .exp file as well. (In some cases, this meant that
the name of a helper module was "taken over" by the main module
of the test case.)
Update all references to the moved modules.
General updates to programming style, such as
- replacing DCG notation with state var notation
- replacing (C->T;E) with (if C then T else E)
- moving pred/func declarations to just before their code
- replacing io.write/io.nl sequences with io.write_line
- replacing io.print/io.nl sequences with io.print_line
- fixing too-long lines
- fixing grammar errors in comments
tests/hard_coded/Mmakefile:
tests/hard_coded/Mercury.options:
Update all references to the moved modules.
Enable the constant_prop_int test case. The fact that it wasn't enabled
before is probably an accident. (When constant_prop_int.m was created,
the test case was added to a list in the Mmakefile, but that list
was later removed due to never being referenced.)
tests/hard_coded/constant_prop_int.{m,exp}:
Delete the calls to shift operations with negative shift amounts,
since we have added a compile-time error for these since the test
was originally created.

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 debugger tests,
specify the new line numbers in .inp files and expect them in .exp files.
Branches: main
Add support for `try' goals, syntactic sugar on top of the exception handling
predicates in the standard library. The syntax is documented in the reference
manual. Currently one of the proposed try parameters, io(!IO), is implemented.
Try goals are implemented by *two* source-to-source transformations, one at the
parse tree level, then a later one on the HLDS. The reason for this is given
in try_expand.m.
library/ops.m:
Add three new operators: try, catch, catch_any.
library/exception.m:
Add forwarding predicates so that code generated by the try goal
transformation doesn't need to import `univ'.
compiler/prog_item.m:
Add representations of try goals to parse tree.
compiler/prog_io_goal.m:
Parse try goals.
Unrelated: fix spelling of "parameter".
compiler/add_clause.m:
Perform the initial transformation on try goals.
compiler/hlds_goal.m:
Add try goals to HLDS, as shorthand goals.
compiler/try_expand.m:
New module to perform the latter transformation on try goals.
compiler/check_hlds.m:
Import the new module.
compiler/mercury_compile.m:
Call the try_expand pass near the end of the front-end pass.
compiler/module_imports.m:
Implicitly import `exception' if a `try' goal is seen.
compiler/det_analysis.m:
Conform to addition of try goals in HLDS. Make it not wrap a commit
scope around the intermediate try goal (as it might if there are no
outputs) as it is inappropriate.
compiler/prog_util.m:
Conform to parse tree changes.
