4c528d429d Add <<u and >>u to library/{int,uint}*.m ...
... along with their unchecked equivalents. These differ from <<, >> and
their unchecked equivalents in that they take the shift amount as a uint,
instead of an int.

    As above. The unchecked versions have only declarations, since
    these operations have been recognized as builtins for a while now.

NEWS:
    Document the new operations, and the recent change to recognize
    <<u and >>u as single tokens, and fix a typo in a recent addition.

configure.ac:
    Require the compiler to be sufficiently recent to be able to parse
    <<u and >>u as operators.

compiler/options.m:
    Provide a way for a later change to configure.ac to detect the presence
    of this change.

3c3c072a33 Make bitwise op tests' .exp files more readable.

tests/hard_coded/bitwise_uint8.m:
    Most of the expected output files of these test cases were
    easily readable already, but there were some exceptions caused
    by unnecessary differences between their source codes.

    The main problem was with bitwise_uint.m (uint_bitwise.m until recently),
    whose .exp file contained very long lines of the form A op B = C
    where A, B and C could each be 64 bits (and chars) long. Fix this
    by adopting the format used by the other modules:

        A op
        B =
        C

    The other problem was that in some test cases, the indentation had
    an off-by-one bug. They generated output such as

        \ aaaa =
         bbbb

    instead of the much-easier-to-visually-check

        \ aaaa =
          bbbb

    A third, much less important change is the deletion of unnecessary
    blank lines.

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/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.
