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.
