Replace __ with . as the module qualifier symbol.
Replace references to io.state with just io.
Replace DCGs with state variables.
Replace (C->T;E) syntax for if-then-elses with (if C then T else E) syntax.
Replace if-then-elses with switches when possible and where this does not
affect what is being tested.
Replace separate pred and mode declarations with predmode declarations.
Put predicate and function declarations just before the definition
of the predicate or function.
Delete unneeded module qualifications on predicate and function declarations
and definitions.
Update .exp files (and if needed, .inp files) for the line number changes
that result from the above.
For tests that have more than one .exp file and where one of those files
is affected by the above, add a section to the source file header that says
which .exp file is for what grade, with XXXs for the (as yet) unknown parts.

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.

Optimize shallow traced modules by not adding calls to MR_trace to shallow
traced procedures which cannot be called from a deep traced environment.
A shallow traced procedure can be optimized in this way if it is neither
exported from its defining module nor has its address taken.
The main purpose of this optimization is not the avoidance of the cost of the
MR_trace calls as much as it is the restoration of tail recursion optimization.
Previously, compiling a program in a debug grade would disable all tail
recursion in the program (since debug grades require at least shallow tracing
every module). This was a problem because it limited the sizes of the inputs
the debugged program could process before running out of memory. As long as
the procedures that recurse on the input are in the implementation section
of a shallow traced module, this should no longer happen.
compiler/trace_params.m:
Introduce the concept of a procedure's effective trace level. This is
identical to the global trace level, except if the procedure is not
exported and doesn't have its address taken, and the global trace level
is shallow. In that case, we say that the procedure's effective trace
level is none.
Computing a procedure's effective trace level requires its proc_info
and its parent pred_info, so require callers to supply these as
parameters.
compiler/code_info.m:
Store the current pred_info as well as the current proc_info, for
trace parameter lookups.
compiler/continuation_info.m:
compiler/code_gen.m:
Record the required trace parameters of a procedure in its layout
structure, since it can no longer be computed from the global trace
level.

trying to compute them from the global trace level.

tests/debugger/shallow.m:

tests/debugger/shallow.{inp,exp*}:
Divide the old test case in shallow.m in two. The top level predicates
stay in shallow.m and continue to be shallow traced. The two bottom
predicates move to shallow2.m and are now deep traced.
The new test input checks whether the debugger can walk across the
stack frames of procedures in shallow traced modules whose effective
trace level is "none" (such as queen/2).

Compile the files in the library directory with --trace minimum by default,
which has no effect in non-debugging grades and causes the library to be
shallow traced, not deep traced, in debugging grades.
This is probably what most users want, and it makes it much easier to
maintain the expected output of the debugging test cases in debugging grades.

Add --trace minimum to MCG.
