compiler/mode_errors.m:
When printing insts in error messages, use predicates specifically
designed for that purpose.
The insts output by these predicates improve on the existing output
in the following ways.
- We now show the structure of complex insts through indentation.
- We now show both the name of named insts, and their expansion.
Sometimes, you need the expanded inst to understand the error message,
in the case of recursive insts, you cannot expand them forever.
Since the expansion *has* to refer to the inst name, showing that name
at the *start* of the expansion is necessary to allow readers to
understand the inst.
- We now eliminate the module qualification from the names of function
symbols. The module qualifiers on function symbols are specified
by the type, not the inst, of the relevant term, and if we get to
the point of mode analysis having been run, then the predicate
we are generating errors for must be *type* correct, though obviously
it is not *mode* correct.
- We now eliminate the module qualification from names of named insts
if the module qualifier is the name of the module being compiled.
This is a common case, and in these cases, the module qualifier
in the error message acts as clutter, making it *harder* to read.
- We now avoid printing parentheses that humans never need, but which
the parser sometimes does, and which the existing inst output predicates
therefore had to print.
- Higher order insts contain the modes of the function or predicate.
We now print the builtin modes as e.g. "in" instead of the old
"free >> ground".

Add some utility predicates now needed by mode_errors.m.
