Fix encoding of primitive constants when cross-compiling

QV4::Primitive is using host value encoding, which can differ from the
target. The source of QV4::Primitive in the code generator is usually
IR::Const, transformed via convertToValue(). That function becomes a
template that converts to a simple target primitive type.
