Also, fix threshold for 'Big' register saves.

d22920aae8 Revert commit 131781, to see if it fixes the x86-64 dragonegg buildbot. 
Original log message:
When BasicAA can determine that two pointers have the same base but
differ by a dynamic offset, return PartialAlias instead of MayAlias.
See the comment in the code for details. This fixes PR9971.

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 
and an exception handler. Handle that case.

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

43299776d7 Change the order fixed objects are created in MipsTargetLowering::LowerCall in 
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.
