[Bug rtl-optimization/20370] New: dead_or_predictable doesn't resize reg_n_info

["amylaar at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

dead_or_predictable calls propagate_block without checking first if there
is suddicient space in reg_n_info.  That can lead to memory corruption.
