5ec65765e6 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.

347e0f26be Fix our handling of the warning when one tries to pass a 
non-POD/non-trivial object throuugh a C-style varargs. The warning
itself was default-mapped to error, but can be downgraded, but we were
treating it in Sema like a hard error, silently dropping the call.

Instead, treat this problem like a warning, and do what the warning
says we do: abort at runtime. To do so, we fake up a __builtin_trap()
expression that gets evaluated as part of the argument.

fda5dc4968 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".

643c922e66 Introduce the -fdiagnostics-format=xxx option to control how Clang 
prints the file, line, and column of a diagnostic. We currently
support Clang's normal format, MSVC, and Vi formats.

Note that we no longer change the diagnostic format based on
-fms-extensions.

8e8f59bdfb 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.

faeb520c97 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.

0837692ac6 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.

6282a4a1d3 This is a simplified (and superior) implementation of __invoke, __invokable and __invoke_of. It is superior in that __invoke now handles reference qualified member functions whereas the previous implementation did not. And it simply has less infrastructure in its implementation. I'm still learning how to program in C++11 (and probably will be for a long time). This change does not impact the behavior we're seeing in http://llvm.org/bugs/show_bug.cgi?id=9975
