Sean Dewar 41d0e7af20 vim-patch:8.2.3601: check for overflow in put count does not work well
Problem:    Check for overflow in put count does not work well.
Solution:   Improve the overflow check. (Ozaki Kiichi, closes vim/vim#9102)
fa53722367

Add some casts as Nvim uses size_t variables in some places.

We could technically adjust the logic to check for overflow outside of size_t's
range, but it's much easier to just port the patch exactly (also means we can
use the same tests).

v:sizeoflong is N/A, so convert the 64-bit tests to Lua and use the FFI to check
long's size.
