First pass at emitIAS for branches and binding labels
Currently not testing fixups of forward branches and
instead streaming a ".byte (foo - (. + 1))" or
".long (foo - (. + 4))". It should be supported once
emitIAS() delays writing things out until after the
function is fully emitted (and therefore forward labels
have all been bound).
