Add ops for creating and accessing 64 bit ints as dwords.

Browse Source 
runtime/mercury_int.h:
    Add macros to create double-word int64s/uint64s from two words,
    and to access each word of a double-word int64 or uint64.

    Put the int64 and uint64 versions of the same macro next to each other.

    Add parentheses where this clarifies code.

runtime/mercury_float.h:
    Note the parallel to the new code in mercury_int.h.

    Add comments to #elses and #endifs that repeat the condition of the
    initial #if, to make the code easier to read.

    Put macro definitions into a consistent order.

    Use lower-case names for macro parameters, since this is standard.

    Add parentheses where this clarifies code.

    Delete a macro definition that is now in mercury_std.h.

runtime/mercury_std.h:
    Move a macro here from mercury_float.h, since mercury_int.h now
    uses it too.

runtime/mercury_memory.h:
    Improve some comments.

compiler/builtin_ops.m:
    Add operations to create double-word int64s/uint64s from two words,
    and to access each word of a double-word int64 or uint64.
    These correspond to the new macros in mercury_int.h.
    The new operations are not used yet.

compiler/bytecode.m:
compiler/c_util.m:
compiler/erl_call_gen.m:
compiler/llds.m:
compiler/llds_out_data.m:
compiler/ml_global_data.m:
compiler/mlds_to_c.m:
compiler/mlds_to_cs.m:
compiler/mlds_to_java.m:
compiler/opt_debug.m:
    Conform to the change to builtin_ops.m.
