Unconditionally set DONT_BREAK_DEPENDENCIES in scheduling flags.

The code to break dependencies does not appear to provide a win under
any circumstance and is often harmful.  Disable it completely pending
further investigation.

    gcc/

	* config/mips/mips.cc (mips_set_sched_flags): Set
	DONT_BREAK_DEPENDENCIES unconditionally.
