c7caf6b7a9 ENHANCED: CLP(ℤ): Reduce redundant propagator invocations during all_distinct/1 filtering 
First, the current propagator is now logged and not re-triggered
during filtering. Second, and more significantly, all neq_num/2
constraints are scheduled and processed before more global constraints
are invoked. In this way, all the distilled information can be taken
into account by subsequently invoked global constraints.

These changes yield a 3-fold improvement in several Sudoku instances,
and a significant runtime reduction in social golfer instance 8-4-9.

b905d2758d fix type_error with instantiated EOF -1 byte literal in get_byte/2 
According to ISO Prolog, get_byte/2 predicate can receive an
instantiated input byte:

http://www.gprolog.org/manual/html_node/gprolog037.html#sec156

    get_byte(+stream_or_alias, ?in_byte)

Since in_byte can be -1 if EOF is reached, instantiating it with -1
should work but does not because the implementation is trying to convert
it to a u8 which is unsigned:

?- open("/dev/null", read, S, [type(binary)]), get_byte(S, -1).
   error(type_error(in_byte,-1),get_byte/2).

This commit adds an extra check for -1 before checking for a valid u8
instantiated value if in_byte is an input:

?- open("/dev/null", read, S, [type(binary)]), get_byte(S, -1).
   S = '$stream'(0x55601e65c998).

Closes #1625

a9a06b5297 Fix xor/2 type error reporting wrong argument 
If first argument n1 in xor/2 is of wrong numerical type, the match
patterns fall through to a catch all case that reports the second
argument in the type error.

Fixes #1626

`xor/2 function reports the wrong argument in type error #1626`
