Zoltan Somogyi b560f66ab9 Move four modules from check_hlds.m to hlds.m.
After this, I think all modules in the check_hlds package belong there.

compiler/inst_match.m:
compiler/mode_test.m:
    Move these modules from the check_hlds package to the hlds package
    because most of their uses are outside the semantic analysis passes
    that the check_hlds package is intended to contain.

compiler/inst_merge.m:
    Move this module from the check_hlds package to the hlds package
    because it is imported by only two modules, instmap.m and inst_match.m,
    and after this diff, both are in the hlds package.

compiler/implementation_defined_literals.m:
    Move this module from the check_hlds package to the hlds package
    because it does a straightforward program transformation that
    does not have anything to do with semantic analysis (though its
    invocation does happen between semantic analysis passes).

compiler/notes/compiler_design.html:
    Update the documentation of the goal_path.m module. (I checked the
    documentation of the moved modules, which did not need updates,
    and found the need for this instead.)

compiler/*.m:
    Conform to the changes above. (For many modules, this deletes
    their import of the check_hlds package itself.)
