Julien Fischer f80463dbcb Add builtin 64-bit integer types -- Part 2.
Replace placeholder types with int64 and uint64 as appropriate throughout the
system.

Enable support for 64-bit integer literals in the compiler.

Add initial library support for 64-bit integers.

configure.ac:
     Check that the bootstrap compiler recognises int64 and uint64 as
     builtins.

library/int64.m:
library/uint64.m:
     Populate these two modules to the extent that we can now run
     basic tests of 64-bit integer support.

     Note that since the bootstrap compiler will not recognise
     64-bit integer literals, any such literals are current written
     as conversions from ints; this will be replaced once this change
     has bootstrapped.

library/private_builtin.m:
    Replace the placeholder definitions for builtin unification and
    comparison of 64-bit integers with their actual definitions.

library/integer.m:
    Add procedures for converting integers to- and from int64 and uint64.

library/string.m:
    Add functions for converting 64-bit integers into strings.

library/io.m:
    Add predicates for writing 64-bit integers to text streams.
    (Support for 64-bit integers with binary streams will be done
    separately.)

library/stream.string_writer.m:
    Add put_int64/4 and put_uint/64.

    Extend the implementations of print and write to cover int64 and
    uint64.

library/pprint.m:
    Make int64 and uint64 instances of the doc/1 type class.

library/erlang_rtti_implementation.m:
library/rtti_implementation.m:
    Handle int64 and uint64 properly in deconstruct.

library/term.m:
    Add functions for converting 64-bit integers into terms.

library/term_conversion.m:
    Support int64 and uint64 in univ -> term conversion.

library/Mercury.options:
    Avoid a warning about the import of the require being
    unused in the int64 and uint64 modules.  It *is* used,
    but only in the definitions used by the Erlang backend.

compiler/superhomogeneous.m:
     Accept 64-bit integer literals.

compiler/c_util.m:
     In C, write out the value of the min_int64 as the symbolic
     constant INT64_MIN.  This expands in such a way as to avoid
     generating warnings from the C compiler.

compiler/builtin_ops.m:
compiler/bytecode.m:
compiler/elds.m:
compiler/elds_to_erlang.m:
compiler/hlds_data.m:
compiler/hlds_out_util.m:
compiler/llds.m:
compiler/llds_out_data.m:
compiler/lookup_switch.m:
compiler/mercury_to_mercury.m:
compiler/mlds.m:
compiler/mlds_to_cs.m:
compiler/mlds_to_java.m:
compiler/opt_debug.m:
compiler/parse_tree_out_info.m:
compiler/parse_tree_to_term.m:
compiler/prog_data.m:
compiler/prog_out.m:
compiler/prog_rep.m:
     Replace the use of int as a placeholder with int64 or uint64 as
     appropriate.

    Extend this test to cover 64-bit integers.
