Levi Cameron 0921310ca5 More work on the bytecode interpreter.
With these changes, it now passes all tests/general/* test cases
  except those with floats.

  Changes to the compiler:
  - Added extra argument to test instruction (string comparisons were
    being treated as integer comparisons; properly deals with different
    atomic type unifications now)
  - Changed bytecode stub functions

  Changes to the bytecode interpreter:
  - Cleaned up comments
  - Forked part of mb_machine to mb_exec
  - Added support for submodules
  - Added support for nondet procedures
  - Added support for cc_xxx procedures
  - Finished higher order calls
  - Added (very basic) debug interface
  - Added support for type information
  - Added memory corruption checking
  - Changed machine state dump formatting
  - Fixed bug in nested switches
  - Resolved builtin__unify and builtin_compare failures
  - Modified bytecode tags generation so .c & .m tag files are separate
  - Header usage rationalised

  Changes to test suite:
  - Added test cases for the bytecode interpreter.
  - More work on the bytecode interpreter.

bytecode/Mmakefile:
        Modified bytecode tags generation so .c & .m tag files are separate.
        mb_machine split into mb_exec.
        test file renamed to simple.m (copy over tests/simple??.m to test).

bytecode/TODO:
        Updated.

bytecode/mb_basetypes.h:
        Removed redundant MB_WORD_BITS (use MR_WORDBITS instead).

bytecode/mb_bytecode.h:
bytecode/mpb_bytecode.c:
        Formatting changes
        Third test instruction argument added.

bytecode/mb_disasm.h:
bytecode/mb_disasm.c:
        Formatting changes.
        Third test instruction argument added.
        Added MB_FMT_INTWIDE.

bytecode/mb_exec.h:
bytecode/mb_exec.c:
bytecode/mb_machine.h:
bytecode/mb_machine.c:
        mb_machine* split into mb_exec* and mb_machine*.
        Almost all instructions now work (see important changes above).

bytecode/mb_interface.h:
bytecode/mb_interface.c:
        Added nondet stub functions.
        Added functions to lookup builtin compiler procedures:
                do_redo, do_fail, __unify, __compare.
        Removed old debugging code.
        Stack layout changed to support nondet procedures.

bytecode/mb_interface_stub.c:
bytecode/mb_interface_stub.h:
        Split off bare minimum of includes for bytecode stubs.
        Added nondet stubs.

bytecode/mb_machine_show.c:
        Made code cleaner (added subfunctions for MB_show_state).
        Added variable names to machine state dump.

bytecode/mb_mem.h:
bytecode/mb_mem.c:
        Added limited memory corruption checking.

bytecode/mb_module.h:
bytecode/mb_module.c:
        Swapped order of temps & vars on stack.
        Fixed nested switches causing random crashes.
        Added nested module support.

bytecode/test/simple??.m:
        Various test files - just to check that it doesn't crash.
        (Most do not output anything & must be verified by stepping through
        manually).

compiler/bytecode.m:
compiler/bytecode_gen.m:
        Added extra argument to test instruction (otherwise
        string comparisons would be treated as integer comparisons).

compiler/code_gen.m:
        Changed call structure name in bytecode stub to resolve
        issues with illegal characters in C structure names.
        Changed bytecode stub header file name.
