[clang-format] Refine structured binding detection

Summary:
Revision r356575 had the unfortunate consequence that now clang-format never
detects an ObjC call expression after `&&`.

This patch tries harder to distinguish between C++17 structured bindings and
ObjC call expressions and adds a few regression tests.

MISched: Don't schedule regions with 0 instructions

I think this is correct, but may not necessarily be the correct fix
for the assertion I'm really trying to solve. If a scheduling region
was found that only has dbg_value instructions, the RegPressure
tracker would end up in an inconsistent state because it would skip
over any debug instructions and point to an instruction outside of the
scheduling region. It may still be possible for this to happen if
there are some real schedulable instructions between dbg_values, but I
haven't managed to break this.

The testcase is extremely sensitive and I'm not sure how to make it
more resistent to future scheduler changes that would avoid stressing
this situation.

LLVM/llvm 356925cfe/trunk/lib/Sema SemaDecl.cpp SemaExpr.cpp

[Sema][NFCI] Don't allocate storage for the various CorrectionCandidateCallback unless we 
are going to do some typo correction

The various CorrectionCandidateCallbacks are currently heap-allocated
unconditionally. This was needed because of delayed typo correction.
However these allocations represent currently 15.4% of all allocations
(number of allocations) when parsing all of Boost (!), mostly because
of ParseCastExpression, ParseStatementOrDeclarationAfterAttrtibutes
and isCXXDeclarationSpecifier. Note that all of these callback objects
are small. Let's not do this.

Instead initially allocate the callback on the stack, and only do a
heap allocation if we are going to do some typo correction. Do this by:

1. Adding a clone function to each callback, which will do a polymorphic
   clone of the callback. This clone function is required to be implemented
   by every callback (of which there is a fair amount). Make sure this is
   the case by making it pure virtual.

2. Use this clone function when we are going to try to correct a typo.

This additionally cut the time of -fsyntax-only on all of Boost by 0.5%
(not that much, but still something). No functional changes intended.

llvm-objcopy previously knew nothing about data in segments that wasn't

this patch causes llvm-objcopy to start preserving this data. Data in

[libc++][CMake] Allow merging libc++abi.a into libc++ even on Apple platforms

Summary:
I can't see a good reason to disallow this, even though it isn't the
standard way we build libc++ for Apple platforms.

Making this work on Apple platforms requires using different flags for
--whole-archive and removing the -D flag when running `ar` to merge
archives because that flag isn't supported by the `ar` shipped on Apple
platforms. This shouldn't be an issue since the -D option appears to be
enabled by default in GNU `ar`.

Minidump: Use minidump constants defined in llvm

This patch begins the process of migrating the "minidump" plugin to the
minidump parser in llvm. The llvm parser is not fully finished yet, but
even now, a lot of things can be switched over. The gradual migration
process will allow us to easier detect if things break than doing a big
one-step migration. Doing it early will allow us to make sure that the
llvm parser fits the use case that we need in lldb.

In this patch I start with the various minidump constants, which have
their llvm equivalent. It doesn't contain any functional changes. The
diff just reflects the different naming of things in llvm.
