* rs6000-core.c: Support 64-bit core files, support pre-4.3 core
files on AIX 4.3. (read_hdr): New function. (rs6000coff_core_p): Store mstsave or __context64 struct instead of trying to extract individual registers. Set abfd->arch_info to match the architecture that created the core file. (rs6000coff_get_section_contents): Delete. * xcoff-target.h (rs6000coff_get_section_contents): Delete.
