[perl #127933] [BUG][REPL] int# bug in REPL

[Christian Bartolomaeus via RT]

Just a note: This seems to be a specific problem with Moar:

$ ./perl6-j
[...]
> my int8 $i = 0x78;
120
> my int8 $j = 0x78;
120
>

I'm going to tag this ticket with [MoarVM]. Or should the ticket be moved to 
the Github repo for MoarVM?
