go/types, go/constant: handle infinities as unknown values With this change, constant literals (and results of constant operations) that internally become infinities are represented externally (to go/constant) as "unknown" values. The language has no provisions to deal with infinite constants, and producing unknown values allows the typechecker to report errors and avoid invalid operations (such as multiplication of zero with infinity). Fixes #20583.
