For type switches using a short variable declaration of the form
switch t := x.(type) {
case T1:
...
go/types doesn't declare the symbolic variable (t in this example)
with the switch; thus such variables are not found in types.Info.Defs.
Instead they are implicitly declared with each type switch case,
and can be found in types.Info.Implicits.
Adjust the shadowing code accordingly.
Added a test case to verify that the issue is fixed, and a test
case verifying that the shadowing code now considers implicitly
declared variables introduces in type switch cases.
While at it, also fixed the (internal) error reporting to provide
more accurate information.
Fixe #26725.
