cmd/compile/internal/noder: avoid ir.Node temps in FixValue
Instead of constructing an untyped basic literal IR node, having
typecheck convert it and return a new one, only to extract the
constant.Value; just have typecheck export the underlying value
conversion function, so we can call it directly.
