which .exp file is for what grade, with XXXs for the (as yet) unknown parts.

Fix some bugs in my previous diff that optimized away stack slots storing
dummy values that manifested themselves as warnings from the C compiler
about integers too big to fit into 8 or 16 bits being implicitly truncated.
They did not lead to the failure of any test case, since it doesn't matter
whether the debugger gets the values it ignores (I/O states or stores)
from valid stack slots or not.
When generating RTTI for gc and the debugger, the compiler had three places
that generated references to stack slots: the return sites of calls, resume
points, and trace events. The previous diff updated only the first of these.
This diff updates the other two, and ensures there are no more.
Since the debugger needs to know whether a procedure has a pair of I/O state
arguments (e.g. when performing a retry), we add a field to proc layouts
to hold this information.
runtime/mercury_grade.h:
Increment the debug grade runtime compatibility version number
to reflect the change in layout structures.
runtime/mercury_stack_layout.h:
Add an extra field to proc layouts to specify flags. At the moment,
the only flag says whether the procedure has a pair of I/O state
arguments.
Add an extra field to proc layouts to specify the trace level of a
procedure. This used to be the same as the module's trace level,
but one of my bug fixes a couple of months ago broke that link.
We don't yet use this field, but it makes sense to do it at the same
time as the increment of the compatibility version number.
compiler/continuation_info.m:
Attach to every description of a live value a description of where
in the compiler that description was created.
Rename the type involved to avoid an ambiguity.
Ignore dummy types when generating resume layouts.
Add some sanity checks.
Add new fields to the continuation_info data structure to allow
stack_layout.m to fill in the new fields in proc layout structures.
compiler/trace.m:
Do not generate references to dummy values at trace events,
except at call ports. At those ports, all live variables should
be in registers.
compiler/stack_layout.m:
Make the check for whether a value fits into an unsigned 8 bit value
a direct rather than an indirect one. The indirect one assumed that
stack slot numbers are all positive, which is now a bad assumption.
Check for negative stack slot numbers in all RTTI stack slot
descriptions.
Fill in the two new slots in proc layout structures.
compiler/layout.m:
Reserve space for the two new slots in proc layout structures.
compiler/layout_out.m:
Output the two new slots in proc layout structures.
compiler/code_gen.m:
Preserve the information needed by stack_layout.m for the two new
fields.
compiler/llds_out.m:
Add some code that ensures that we never output an integer constant
that doesn't fit into the range of its type. Since this code is
executed many millions of times, it is designed to be enabled only
when the checking is manually enabled. It is normally off, but I got
a clean bootcheck in the debug grade (which is the best stress test)
with it enabled.
compiler/trace_params.m:
Update a comment.
compiler/code_info.m:
Export a function for use by trace.m.
compiler/hlds_pred.m:
Export a predicate for use by stack_layout.m.

overhead if it is not enabled.

Remove call depth numbers from standardized event printing. This will make
maintaining the debugger test cases easier since a lot of the expected outputs
differ only in the call depth of their events, because of deep tracing of the
standard library in the decldebug grade.
Not all the debugger tests are run with standardized event printing, so
printing of call depths will still be exercised.

Change the mdb `print' command so that it invokes the non-interactive
version of the term browser, and change the way the browser is invoked
so that the browser state is preserved across multiple invocations
of `print' or `browse' in a single mdb session.
browser/browse.m:
Make `browser_state' an abstract type.
Add new predicate `browse__init_state' to initialize that ADT.
Change the interface to `browse__browse' so that it takes and
returns the old and new browser_states.
Add a new predicate `browse__print' to replace the old
`browse__portray_root' predicate; this is the non-interactive
version of the browser. It calls io__write_univ if the term
is small enough, and browse__portray (with flat format) otherwise.
Export the `browse__print' and `browse__init_state' predicates to C.
Delete the predicates for formatting terms as strings, since that
code was a potential double-maintenance problem and was not needed.
library/io.m:
Export `io__write_univ', for use by browser/browse.m.

Change the `browse' and `print' mdb commands to use the new

calling browser__browse and io__print (respectively), and don't
print a newline afterwards, since the browser does that itself.
