Fix seg-fault in readelf when decoding corrupt IA64 unwind information.
PR binutils/18420
* ia64-unwind.c (unw_decode): Add end parameter. Pass parameter
on to decode functions.
(unw_devode_p2_p5): Pass end paraemter to UNW_DEC_SPILL_MASK.
(UNW_DEC_SPILL_MASK): Add end parameter. Check that unw_rlen does
not take us beyond the end of the buffer.
* ia64-unwind.h (unw_decode): Update prototype.
* readelf.c (dump_ia64_unwind): Pass end pointer to unw_decode.
