Previously, when a function signature had defined a non-final variadic
parameter, the error message always referred to the type associated with that
parameter. However, if the offending parameter's name was part of an identifier
list with a variadic type, one could misinterpret the message, thinking the
problem had been with one of the other names in the identifer list.
func bar(a, b ...int) {}
clear ~~~~~~~^ ^~~~~~~~ confusing
This change updates the error message and sets the column position to that of
the offending parameter's name, if it exists.
Fixes #28450.
