123 +> (1 +< 64)
Cannot unbox 65 bit wide bigint into native integer

This is less than awesome. The correct answer for a too-big-to-unbox
right-shift distance is trivial to obtain and to represent, so this
could easily return the correct answer.

Made error a little more awesome in f6091476486d29c8886da .

$ 6 'say 123 +< (1 +< 64)'
Big integer 18446744073709551616 not yet supported on righthand side of '+<‘
operator

I assume this will want to be fixed at either the NQP level, or perhaps in rakudo core. But probably not before 6.c, so felt like a better error message is the best we can do atm.
