For implementing interface to empty interface conversion, the compiler
generate code like:
var res *uint8
res = itab
if res != nil {
res = res.type
}
However, itab has type *uintptr, so the assignment is broken. The
problem is not shown up, until CL 450215, which call typecheck on this
broken assignment.
To fix this, just cast itab to *uint8 when doing the conversion.
Fixes#56768
