Re: [PATCH]: Fix bootstrap compile time blowout on x86_64.

Hi!

Thanks to Jan Hubicka an issue with compile time blowout came up.  Over
80% of insn-attrtab.c compile time is spent in haifa-sched.c: check_cfg
() function which does sanity check of the whole CFG.  There are three
callers of check_cfg () at the moment: sched_init (), schedule_block ()
and sched_finish ().  While calls from sched_{init, finish} () are done
once per function the call from schedule_block () is invoked for every
single basic block.  Leaving only two of the three calls - sched_{init,
finish} () - will pretty much solve the problem.  Please find the patch
attached.

OK for trunk and gcc-4_2-branch?

:ADDPATCH scheduler:

This is ok.
