AFAICS, the internal definition of integer is "a number that after
being cast into an int, and back to lua_Number, remains the same".
That huge number would certainly overflow even 64bit integers

Besides, a 53bit index would make an immense array (if a TValue is
8bytes, 2^53*8=72057594037927936bytes = 64Petabytes), so there's a
2^24 limit on array indexes, so no danger of 'accidental'
integerization of numbers :-)
