alpha-vms: Sanity check ETIR__C_CTL_DFLOC index
I doubt anyone will want to create more than 16M debug location
entries. If there is no bound the object format allows for 32-bit
indices and of course fuzzers find that and attempt allocation of up
to a 16G byte array. The patch also fixes potential integer overflows
in calculating the array size.
* vms-alpha.c (dst_define_location): Limit size of dst_ptr_offsets
array.
(_bfd_vms_slurp_object_records): Rename "err" to "ok".
