It's better to do this in codegen, mul.with.overflow(X, 2) is more canonical because it has only one use on "X".

Also, add an 'Emitted' member to the MCWin64EHUnwindInfo struct. It will be
needed later.

preparation for reversing StackDirection.

Fixed objects are created in the following order:  
 1. Incoming arguments passed on stack.
 2. va_arg objects (include both arguments that are passed in registers and
    pointer to the location of the first va_arg argument).
 3. $gp restore slot.
 4. Outgoing arguments passed on stack.
 5. Pointer to alloca'd space.

No functionality enabled by default. Use -disable-iv-rewrite.
Extended IVUsers to keep track of the phi that represents the users' IV.
Added the WidenIV transform to replace a narrow IV with a wide IV
by doing a one-for-one replacement of IV users instead of expanding the
SCEV expressions. [sz]exts are removed and truncs are inserted.

There's really nothing to implement. All this really does is swap to a
pseudo-section that later gets written to the unwind info struct. That
needs to be implemented in the object streamers.
