[wide-int] Rename a function to match its type

[Richard Sandiford]

wide_int_type_size_in_bits returns an offset_int (previously an addr_int)
rather than a wide_int, so this patch renames it accordingly.

Tested on powerpc64-linux-gnu and by rerunning the assembly comparison.
OK to install?

Thanks,
Richard
