IA64: Use early_parm to handle mvec_name and nomca
I'm not sure of the worthiness of this idea, so please consider it an RFC. Its key merits are: * Reuse existing infrastructure * Greatly tightens up the parsing of nomca * Greatly simplifies the parsing of machvec Addition cleanup (moving setup_mvec() to machvec.c) by Ken Chen.
