[perl #124559] Roast rakudo skip/todo test:./S02-literals/numeric.t line:20 reason: 'aborts nqp-j'

[Christian Bartolomaeus via RT]

I unfudged some of the skipped tests with commit 
https://github.com/perl6/roast/commit/0aa3fde915

The only test not passing (fudged 'todo') fails because of the following:

$ perl6-j -e 'say <0x01/0x02>'
Attempt to divide by zero using div
  in block <unit> at -e:1

This works, though:

$ perl6-j -e 'say 0x01/0x02'
0.5
