84086fd689 Eliminate the need for ExpandOp to set 'needsanotheriteration', as it already 
relegalizes the stuff it returns.

Add the ability to custom expand ADD/SUB, so that targets don't need to deal
with ADD_PARTS/SUB_PARTS if they don't want.

Fix some obscure potential bugs and simplify code.

3b5a984065 Instead of making callers of ExpandLibCall legalize the result, make 
ExpandLibCall do it itself.

d2c6fbef4a Remove TLI.LowerReturnTo, and just let targets custom lower ISD::RET for 
the same functionality.  This addresses another piece of bug 680.  Next,
on to fixing Alpha VAARG, which I broke last time.

69d30b1c55 If scheduler choice is the default (-sched=default), use target scheduling 
preference to determine which scheduler to use. SchedulingForLatency ==
Breadth first; SchedulingForRegPressure == bottom up register reduction list
scheduler.
