compiler/mode_errors.m:
Replace the two existing options for coerce mode errors with one
that includes:
- the path to the input subterm where the error was detected
- the type of the input subterm
- the target type that the subterm should be converted to
- the reason for the error
compiler/modecheck_coerce.m:
Modify the code to produce the above information.
Semidet predicates that previously failed when an error is detected
are changed to det predicates that return the error information.
In a couple of places where predicates previously would fail,
we now abort because the conditions should not occur.
compiler/hlds_out_util.m:
Describe coerce as "coerce expression" (shows up in mode errors).
