The main aim of this change is to make the overall, high-level structure of the compiler clearer, and to encourage better encapsulation of the major components. compiler/libs.m: compiler/backend_libs.m: compiler/parse_tree.m: compiler/hlds.m: compiler/check_hlds.m: compiler/transform_hlds.m: compiler/bytecode_backend.m: compiler/aditi_backend.m: compiler/ml_backend.m: compiler/ll_backend.m: compiler/top_level.m: New files. One module for each of the major components of the Mercury compiler. These modules contain (as separate sub-modules) all the other modules in the Mercury compiler, except gcc.m and mlds_to_gcc.m. Mmakefile: compiler/Mmakefile: Handle the fact that the top-level module is now `top_level', not `mercury_compile' (since `mercury_compile' is a sub-module of `top_level'). compiler/Mmakefile: Update settings of *FLAGS-<modulename> to use the appropriate nested module names. compiler/recompilation_check.m: compiler/recompilation_version.m: compiler/recompilation_usage.m: compiler/recompilation.check.m: compiler/recompilation.version.m: compiler/recompilation.version.m: Convert the `recompilation_*' modules into sub-modules of the `recompilation' module. compiler/*.m: compiler/*.pp: Module-qualify the module names in `:- module', `:- import_module', and `:- use_module' declarations. compiler/base_type_info.m: compiler/base_type_layout.m: Deleted these unused empty modules. compiler/prog_data.m: compiler/globals.m: Move the `foreign_language' type from prog_data to globals. compiler/mlds.m: compiler/ml_util.m: compiler/mlds_to_il.m: Import `globals', for `foreign_language'. Mmake.common.in: trace/Mmakefile: runtime/Mmakefile: Rename the %.check.c targets as %.check_hdr.c, to avoid conflicts with compiler/recompilation.check.c.
