Zoltan Somogyi d4861d739d Allow formatting of sized integers.
library/string.m:
    Add {i,u}{8.16,32,64} as function symbols in the poly_type type,
    each with a single argument containing an integer with the named
    signedness and size.

    The idea is that each of these poly_type values works exactly
    the same way as the i(_) poly_type (if signed) or the u(_) poly_type
    (if unsigned), with the exception that the value specified by the call
    is cast to int or uint before being processed.

library/string.parse_runtime.m:
    Parse the new kinds of poly_types. Change the representation of the result
    of the parsing to allow recording of the sizes of ints and uints.

    Put the code that does the parsing into a predicate of its own.

library/string.format.m:
    Do a cast to int or uint if the size information recorded in the
    specification of a signed or unsigned integer value calls for it.

    Provide functions to do the casting that do not require the import
    of {int,uint}{8,16,32,64}.m. This is to allow the compiler to generate
    calls to do such casts without having to implicitly import those modules.

    Abort if a 64 bit number is being cast to a 32 bit word.

compiler/parse_string_format.m:
    Make the same changes as in string.parse_runtime.m, mutatis mutandis.

compiler/format_call.m:
    Handle the new kinds of poly_types by adding a cast to int or uint
    if necessary, using the predicates added to library/string.format.m.

    Use a convenience function to make code creating instmap deltas
    more readable.

library/io.m:
library/pprint.m:
library/string.parse_util.m:
tests/invalid/string_format_bad.m:
tests/invalid/string_format_unknown.m:
    Conform to the changes above.

tests/string_format/string_format_d.m:
tests/string_format/string_format_u.m:
    Test the printing of some of the new poly_types.

tests/string_format/string_format_d.exp2:
tests/string_format/string_format_u.exp2:
    Update the expected output of these tests on 64-bit platforms.

tests/string_format/string_format_lib.m:
    Update programming style.
