32a43cc0fc Reapply commit 143028 with a fix: the problem was casting a ConstantExpr Mul 
using BinaryOperator (which only works for instructions) when it should have
been a cast to OverflowingBinaryOperator (which also works for constants).
While there, correct a few other dubious looking uses of BinaryOperator.
Thanks to Chad Rosier for the testcase.  Original commit message:
My super-optimizer noticed that we weren't folding this expression to
true: (x *nsw x) sgt 0, where x = (y | 1).  This occurs in 464.h264ref.

8ff2664f2f Add a TODO comment. FastISel works by parsing each basic block from the bottom 
up.  Thus, improving the support for compares is goodness because it increases
the number of terminator instructions we can handle.  This creates many more 
opportunities for target specific fast-isel.

e840e88239 This commit introduces two fake instructions MORESTACK_RET and 
MORESTACK_RET_RESTORE_R10; which are lowered to a RET and a RET
followed by a MOV respectively.  Having a fake instruction prevents
the verifier from seeing a MachineBasicBlock end with a
non-terminator (MOV).  It also prevents the rather eccentric case of a
MachineBasicBlock ending with RET but having successors nevertheless.

Patch by Sanjoy Das.
