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.

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).

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.

Source code was assuming that llvm-config.h would be included somehow but
up to r247253 that added #include "llvm/Support/Compiler.h" to StringRef.h
the config file was not actually included. The inclusion of llvm-config.h
caused a change of behaviour in tools/clang/test/Frontend/source-col-map.c:
previously it would output the original UTF-8 but now it outputs <U+03B1>.

These tests were found by llvm-mc-fuzzer (see http://reviews.llvm.org/D12723)
and verified by checking the disassembler output is accepted by GAS.
The problematic tests from the previous commit have been moved to
valid-xfail.txt for now.
Also, give invalid instructions some coverage. invalid-xfail.txt contains
instructions that should be invalid but successfully disassemble.

While this may seem like a lot of unrelated changes, they all relate back to fixing HasDeclarationMatcher.
This now allows us to write a matcher like:
varDecl(hasType(namedDecl(hasName("Foo"))))
that matches code using typedefs, objc interfaces, template type parameters, injected class names, or unresolved using typenames.

Change the mapping symbol handling to handle the case when the mapping
symbols are prefixed with an arbitrary prefix. This isn't strictly standard
compliance, but if all symbols in an object file is prefixed with objcopy
then the prefix will be added to the mapping symbol also. We still want to
treat these symbols as mapping symbols to get the correct address class data.

Summary:
1. Avoid converting loops that iterate over the size of a container and don't use its elements, as this would result in an unused-result warning.
2. Never capture the elements by value on lambdas, thus avoiding doing unnecessary copies and errors with non-copyable types.
3. The 'const auto &' instead of 'auto &' substitution on const containers now works on arrays and pseudoarrays as well.
4. The error about multiple replacements in the same macro call is now documented in the tests (not solved though).
5. Due to [1], I had to add a dummy usage of the range element (like "(void) *It;" or similars) on the tests that had empty loops.
6. I removed the braces from the CHECK comments. I think that there is no need for them, and they confuse vim.
