This is a trivial issue to fix, just marking it for later.
Windows prints function signatures a bit differently, and the
test expects a specific format.

-force-align-stack.
Also, make changes to the driver so that -mno-stack-realign is no longer
an option exposed to the end-user that disallows stack realignment in
the backend.

realignment should be forced.
With this commit, we can now force stack realignment when doing LTO and
do so on a per-function basis. Also, add a new cl::opt option
"stackrealign" to CommandFlags.h which is used to force stack
realignment via llc's command line.
Out-of-tree projects currently using -force-align-stack to force stack
realignment should make changes to attach the attribute to the functions
in the IR.

We used different conditions to determine if we should emit startproc vs
endproc. Use the same condition to ensure that they will always be
paired.
This fixes PR24374.

The rest of the EH pads are fine, since they have at most one label and
take fewer operands for the personality.
Old catchpad vs. new:
%5 = catchpad [i8* bitcast (i32 ()* @"\01?filt$0@0@main@@" to i8*)] to label %__except.ret.10 unwind label %catchendblock.9
-----
%5 = catchpad [i8* bitcast (i32 ()* @"\01?filt$0@0@main@@" to i8*)]
to label %__except.ret.10 unwind label %catchendblock.9

clang modules, if -dwarf-ext-refs (DebugTypesExtRefs) is specified.
This reimplements r247369 in about a third of the amount of code.
Thanks to David Blaikie pointing this out in post-commit review!

We used to have this magic "hasLoadLinkedStoreConditional()" callback,
which really meant two things:
- expand cmpxchg (to ll/sc).
- expand atomic loads using ll/sc (rather than cmpxchg).
Remove it, and, instead, introduce explicit callbacks:
- bool shouldExpandAtomicCmpXchgInIR(inst)
- AtomicExpansionKind shouldExpandAtomicLoadInIR(inst)

This brings a warning.
cl : Command line warning D9035: option 'Og-' has been deprecated and will be removed in a future release
We should resolve PR11951 to remove this tweak.

When uses of personality functions were moved from LandingPadInst to
Function, we forgot to update SimplifyPersonality(). This patch corrects
that.
Note: SimplifyPersonality() is an optimization which replaces
personality functions with the default C++ personality when possible.
Without this update, some ObjC++ projects fail to link against C++
libraries (seeing as the exception ABI had effectively changed).

These tests were found by llvm-mc-fuzzer (see http://reviews.llvm.org/D12723)
and were verified by checking the disassembler output is accepted by GAS.

This patch adds a runtime check for asan, dfsan, msan, and tsan for
architectures that support multiple VMA size (like aarch64). Currently
the check only prints a warning indicating which is the VMA built and
expected against the one detected at runtime.

The function use_after_scop would iterate from 0 to 1024 and accessing element A[1024] where A has only valid indexes from 0 to 1023. Polly detects the situation of unconditionally undefined behavior and bail out in ScopInfo as non-feasible for optimization.
Other tests add impossible context assumptions as well, hance might show the same problem.
