This fixes alignment of Japanese, Korean and Chinese fullwidth character comments.

The displayed widths of multi-byte fullwidth characters are generally
twice as large as the ASCII characters, but String#size returns only the number of characters.
So if the column comment contains fullwidth multibyte characters, the alignment is broken.

In rails 4, columns do not respond to `bigint?`.  However, in both rails
4 and rails 5, columns do respond to `sql_type`. This way, annotations
should work in both versions.
