4360fd8d6f go/types, types2: use "and not used" instead of "but not used" in error messages
This matches longstanding compiler behavior.

Also, for unused packages, report:

`"pkg" imported and not used`
`"pkg" imported as X and not used`

This matches the other `X declared and not used` errors.

For #55326.

53c4c17b09 [dev.typeparams] all: merge dev.regabi into dev.typeparams
The files below had conflicts that required manual resolution.
The unresolved conflict in noder.go was just in the import
declaration (trivial). All the other conflicts are in tests
where the ERROR regex patterns changed to accomodate gccgo
error messages (incoming from dev.regabi), and to accomodate
types2 in dev.typeparams. They were resolved by accepting the
dev.regabi changes (so as not to lose them) and then by re-
applying whatever changes needed to make them pass with types2.
Finally, the new test mainsig.go was excluded from run.go when
using types2 due to issue #43308.

5f29a7a705 cmd/compile: hint on wrong case-field names in composite literals
Improve the error message for wrong
case-field names in composite literals,
by mentioning the correct field name.

Given the program:
package main

type it struct {
        ID string
}

func main() {
        i1 := &it{id: "Bar"}
}

just like we do for usage of fields, we now
report wrongly cased fields as hints to give:

ts.go:8:14: unknown field 'id' in struct literal of type it (but does have ID)

instead of before:

ts.go:8:14: unknown field 'id' in struct literal of type it

Fixes #22794
