253174bf50 Cleanup of the [SU]ADDO type legalization code. Patch by Duncan!
"It simplifies the type legalization part a bit, and produces better code by
teaching SelectionDAG about the extra bits in an i8 SADDO/UADDO node.  In
essence, I spontaneously decided that on x86 this i8 boolean result would be
either 0 or 1, and on other platforms 0/1 or 0/-1, depending on whether the
platform likes it's boolean zero extended or sign extended."

8ac0d4b4fb - Move conversion of [SU]ADDO from DAG combiner into legalizer.
- Add "promote integer type" stuff to the legalizer for these nodes.

1c55a9c0cc Rename "ADDO" to "SADDO" and "UADDO". The "UADDO" isn't equivalent to "ADDC"
because the boolean it returns to indicate an overflow may not be treated like
as a flag. It could be stored to memory, for instance.

7cdc3c8ad2 Implement the sadd_with_overflow intrinsic. This is converted into
"ISD::ADDO". ISD::ADDO is lowered into a target-independent form that does the
addition and then checks if the result is less than one of the operands. (If it
is, then there was an overflow.)

f209c2cc30 Remove the CycleBound computation code from the ScheduleDAGRRList
schedulers. This doesn't have much immediate impact because
targets that use these schedulers by default don't yet provide
pipeline information.

This code also didn't have the benefit of register pressure
information. Also, removing it will avoid problems with list-burr
suddenly starting to do latency-oriented scheduling on x86 when we
start providing pipeline data, which would increase spilling.

47d1a214a7 Change these schedulers to not emit no-ops. It turns out that
the RR scheduler actually does look at latency values, but it
doesn't use a hazard recognizer so it has no way to know when
a no-op is needed, as opposed to just stalling and incrementing
the cycle count.

e6ed6ecfb0 Introduce two new "add" intrinsics. These return the sum plus a bit indicating
that an overflow/carry occured. These are converted into ISD::[SU]ADDO nodes,
which are lowered in a target-independent way into something sane. Eventually,
each target can implement their own method of checking the overflow/carry flags.
