"stored once" even if its address is compared.

9e7bc05ad7 fix PR9841 by having GVN not process dead loads. This was 
causing it to get into infinite loops when it would widen a 
load (which can necessarily leave around dead loads).

differ by a dynamic offset, return PartialAlias instead of MayAlias.

cd89d4d524 Revert "InstCombine: Turn mul.with.overflow(X, 2) into the cheaper add.with.overflow(X, X)" 
It's better to do this in codegen, mul.with.overflow(X, 2) is more canonical because it has only one use on "X".

321fe74b2d A handler for a function in the Win64 EH scheme can be both an unwind handler

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.
