[PATCH, committed] linux64.h and rs6000.c updates

[David Edelsohn]

	POWER is more appropriate as the default 64-bit processor for GCC
4.0 and dep_insn parameter now is used in rs6000_adjust_cost function.

David

	* config/rs6000/linux64.h (PROCESSOR_DEFAULT64): Default to POWER4.

	* config/rs6000/rs6000.c (rs6000_adjust_cost): dep_insn is used.
