Fix eq and ne tpl function issue

Fix eq and ne tpl function issue

`eq` and `ne` template functions don't work as expected when those are
used with a raw number and a calculated value by add, sub etc. It's
caused by both numbers type differences. For example, `eq 5 (add 2 3)`
returns `false` because raw 5 is `int` while `add 2 3` returns 5 with
`int64`

This normalizes `int`, `uint` and `float` type values to `int64`,
`uint64` and `float64` before comparing them. Other type of value is
passed to comparing function without any changes.
