    print-rtl: Fix printing of CONST_STRING in DEBUG_INSNs [PR93399]

    The following testcase fails to assemble, as CONST_STRING in the
DEBUG_INSNs
    is printed as is, so if it contains \n and/or \r, we are in trouble:
            .loc 1 14 3
            # DEBUG haystack => [si]
            # DEBUG needle => "
    "
    In the gimple dumps we print those (STRING_CSTs) as
      # DEBUG haystack => D#1
      # DEBUG needle => "\n"
    so this patch uses what we use in tree printing for the CONST_STRINGs too.

        * tree-pretty-print.h (pretty_print_string): Declare.
        * tree-pretty-print.c (pretty_print_string): Remove forward
        declaration, no longer static.  Change nbytes parameter type
        from unsigned to size_t.
        * print-rtl.c (print_value) <case CONST_STRING>: Use
        pretty_print_string and for shrink way too long strings.

        * gcc.dg/pr93399.c: New test.
