Janne Blomqvist 7a15726687 Use pointer sized array indices. 
Using pointer sized variables (e.g. size_t / ptrdiff_t) when the
variables are used as array indices allows accessing larger arrays,
and can be a slight performance improvement due to no need for sign or
zero extending, or masking.

Regtested on x86_64-pc-linux-gnu.
