When used with the compiler, types2 will report assignment error
messages that closely match what the compiler type checker (types1)
produces.
Also, mark lhs variables as used in invalid variable initializations
to avoid a class of follow-on errors.
Fixes#48558.

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.
