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.
Construction unifications of partially instantiated values involving direct
argument functors (where the single argument is free) did not generate any code
in both low-level and high-level backends. Incorrect behaviour could result if
the program tried to deconstruct the value at run-time.
Also, in the LLDS backend, such a construction unification did not enter the
variable into the var_state_map, leading to a compiler abort when the variable
is looked up.
compiler/ml_unify_gen.m:
Generate code for constructions of a direct arg functor with free
argument. This amounts to assigning a variable to a tagged null
pointer.
compiler/llds.m:
Add an rval option `mkword_hole', which is like `mkword' but the
pointer to be tagged is unspecified.
compiler/unify_gen.m:
Assign a variable to an `mkword_hole' rval, for a construction
unification of a direct arg functor with a free argument.
Reassign the variable to an `mkword' rval when the argument becomes
bound in a later unification.
compiler/code_info.m:
compiler/var_locn.m:
Add a predicate to reassign a variable from a `mkword_hole' expression
to a `mkword' expression.
compiler/llds_out_data.m:
Write out `mkword_hole' values as a tagged null pointer in C code.
