clang was needlessly duplicating whole memory buffer contents in an attempt to
satisfy unclear ownership semantics. Let's just hide internal LLVM quirks and
present a simple non-owning interface.
The public C API preserves previous behaviour for stability.

Add the new AppContainer characteristic which is import for Windows Store
(Metro) compatible applications. Add the new Control Flow Guard flag to bring
the enumeration up to date with the current values as of Windows 8.1.

At least this answers the question of whether .bc/.ll input processed by the
frontend produces identical output to the original compilation.

Any uses of tools/lto as a static lib should probably move to lib/LTO.
This was also never implemented in the configure build, so this reduces
the differences among the two.

Test that we can consume LLVM bitcode and additionally check that it produces
the same output as a direct compilation.
The feature is crashy and has gone untested until now, but we might as well
provide some coverage as long as it remains in tree.
Also test LL source input in the same way because the existing tests for that
don't look convincing.

both MSP430InstrInfo and MSP430RegisterInfo. Remove unused member
variable StackAlign from MSP430RegisterInfo. Update constructors
accordingly.

This silences false positives (leaks, use of uninitialized value) in simple
code that uses containers such as std::vector and std::list. The analyzer
cannot reason about the internal invariances of those data structures which
leads to false positives. Until we come up with a better solution to that
problem, let's just not inline the methods of the containers and allow objects
to escape whenever such methods are called.
This just extends an already existing flag "c++-container-inlining" and applies
the heuristic not only to constructors and destructors of the containers, but
to all of their methods.
We have a bunch of distinct user reports all related to this issue
(radar://16058651, radar://16580751, radar://16384286, radar://16795491
[PR19637]).

For now I used a separate template for these sub-vector/tuple broadcasts
rather than sharing the mem variants with avx512_int_broadcast_rm.

There is no need to calculate the liveness information for stackmaps. The
liveness information is still available for the patchpoint intrinsic and
that is also the intended usage model.
