go/parser: resolve the type name when parsing a composite lit value
parsePrimaryExpr has to be careful to resolve identifiers used in composite expressions when parsing in LHS mode. It missed the literal type name. Fixes #45136 Change-Id: I3e12f91e3ef5fdb43faa436cdf1240eb3293fe1a Reviewed-on: https://go-review.googlesource.com/c/go/+/304451 Trust: Robert Findley <rfindley@google.com> Run-TryBot: Robert Findley <rfindley@google.com> TryBot-Result: Go Bot <gobot@golang.org> Reviewed-by: Robert Griesemer <gri@golang.org>
