hold register masks. (md_begin): Initialize them to zero. (append_insn): Update mips_gprmask and mips_cprmask. Also add register variables pinfo and prev_pinfo. * config/tc-mips.h (mips_gprmask, mips_cprmask): Declare. * config/obj-ecoff.c (ecoff_frob_file): If TC_MIPS, set gprmask and cprmask from mips_gprmask and mips_cprmask.
