* alpha-nat.c, irix4-nat.c, irix5-nat.c, mipsv4-nat.c,
sparc-tdep.c (supply_gregset, supply_fpregset): Fill inaccessible
registers with zero to handle recent read_register_bytes change.
* irix4-nat.c, irix5-nat.c, mipsv4-nat.c (supply_gregset,
fill_gregset): Fix handling of CAUSE_REGNUM.
* mips-nat.c (store_inferior_registers): Handle unwritable
registers when storing a single register.
* config/mips/tm-irix3.h (CAUSE_REGNUM, BADVADDR_REGNUM):
Fix definitions.
* mdebugread.c (parse_symbol, psymtab_to_symtab_1): Clear
allocated mips_extra_func_info, if the debug info is corrupt,
the PDR to fill it in might be missing.
