Zoltan Somogyi 4ea9695030 Move predicates that find modules' files to find_module.m.
compiler/file_util.m:
compiler/find_module.m:
    As above. Users may specify a module by its module name or
    by its file name, but having the predicates that search
    for a module's source, interface or optimization files by file name
    be in file_util.m while similar predicates that search by module name
    be in find_module.m is suboptimal, since it prevents factoring out
    any commonalities, and makes it harder to spot things that *should*
    be common but arent't.

compiler/check_libgrades.m:
compiler/compile_target_code.m:
compiler/make.module_dep_file.m:
compiler/make.util.m:
compiler/mercury_compile_front_end.m:
compiler/mmc_analysis.m:
compiler/options_file.m:
compiler/parse_module.m:
    Update module imports.
