Julien Fischer f519e26173 Add builtin 64-bit integer types -- Part 1.
Add the new builtin types: int64 and uint64.

Support for these new types will need to be bootstrapped over several changes.
This is the first such change and does the following:

- Extends the compiler to recognise 'int64' and 'uint64' as builtin types.
- Extends the set of builtin arithmetic, bitwise and relational operators
  to cover the new types.
- Adds the new internal option '--unboxed-int64s' to the compiler; this will be
  used to control whether 64-bit integer types are boxed or not.
- Extends all of the code generators to handle the new types.
- Extends the runtimes to support the new types.
- Adds new modules to the standard library intend to contain basic operations
  on the new types.  (These are currently empty and not documented.)

There are bunch of limitations marks with "XXX INT64"; these will be lifted in
part 2 of this change.  Also, 64-bit integer types are currently always boxed,
again this limitation will be lifted in later changes.

    the new types we give them polymorphic arguments.  These can be
    replaced after this change has bootstrapped.

    unboxing.

    Add functions for hashing 64-bit integer types suitable for use
    with the tabling mechanism.

runtime/mercury_tabling.[ch]:
    Add additional HashTableSlot structs for 64-bit integer types.

    Omit the '%' character from the conversion specifiers we pass via
    the 'key_format' argument to the macros that generate the table lookup
    function.  This is so we can use the C99 exact size integer conversion
    specifiers (e.g. PRIu64 etc.) directly here.

runtime/mercury_hash_lookup_or_add_body.h:
    Add the '%' character that was omitted above to the call to debug_key_msg.

doc/reference_manual.texi:
     Add the new types to the list of reserved type names.

     Add the mapping from the new types to their target language types.
     These are commented out for now.

% A type_ctor_details structure contains all the information that the
% runtime system needs to know about the data representation scheme
% used by a type constructor.
%
% There are four alternatives that correspond to discriminated union:
% enum, du, reserved and notag. Enum is for types that define only
% constants. Notag is for types that define only one unary functor.
% Reserved is for types in which at least one functor is represented
% using a reserved value, which may be the address of an object or a
% small integer (including zero). Du is for all other types.
%
% All four alternatives have four kinds of information.
%
% First, an indication of whether the type has user-defined equality or
% not.
%
% Second, a list of descriptors containing all the function symbols
% defined by the type, in declaration order.
%
% Third, a table that allows the runtime system to map a value in
% memory to a printable representation (i.e. to implement the
% deconstruct operation).
%
% Fourth, a table that allows the runtime system to map a printable
% representation to a value in memory (i.e. to implement the
% construct operation).
%
% For types in which some function symbols are represented by reserved
% addresses, the third component is in two parts: a list of function
% symbols so represented, and a table indexed by the primary tag for
% all the other function symbols. The runtime system must check every
% element on the list before looking at the primary tag.
%
% For notag types, the single functor descriptor fills the roles of
% the second, third and fourth components.
