c383dd2c87 eliminate dependence on StandardPasses.h. The code generator's pass pipeline
should eventually convert to PMBuilder, but I don't plan to do this.

c228e6bdea 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.

24f75ab769 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".

7f9c007dce 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.

28ea8de263 Fix PR9978 by adding RIP to GR64_TC so it can be used as an address in PIC code. It
is already in GR64 for the same reasons. Since it isn't allocatable it can't cause
any problems.

66b7b0949f 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.

d58ffb7e7d Add asserts in StringRef to make sure we avoid undefined behavior:
-strlen should not be called with NULL. Also guarantee that StringRef's Length is 0 if Data is NULL.
-memcmp should not be called with NULL (even if size is 0)

3352db291f indvars: Prototyping Sign/ZeroExtend elimination without canonical IVs.
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.

5e5cc95580 "Implement" the HandlerData Win64 EH method in the base MCStreamer.
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.
