alpha-vms: ETIR checks
Better validity checks, and remove a fuzzer vulnerability of sorts that
targeted the store-immediate-repeat command with a zero length but
very large repeat counts to chew cpu.
* vms-alpha.c (_bfd_vms_slurp_etir): Check bound for the current
command against cmd_length, not the end of record. For
ETIR__C_STO_IMMR check size against cmd_length, mask repeat count
to 32-bits and break out on zero size. Add ETIR__C_STC_LP_PSB
cmd_length test.
