* Treat _Atomic(T) as a literal type if T is a literal type.
* Evaluate expressions of this type properly.
* Fix a lurking bug where we built completely bogus ASTs for converting to
_Atomic types in C++ in some cases, caught by the tests for this change.

This is important if the user has multiple Xcodes installed on their
system -- we use xcodebuild to do a version check, and therefore we need
to make sure we match the actual build command.

Currently, blocks instantiated in templates lose their "signature as
written"; it's not clear if this is intentional. Change the analyzer's
use of BlockDecl::getSignatureAsWritten to check whether or not the
signature is actually there.

Instead of selectively storing some changes and directly generating
replacements for others, we now notify the WhitespaceManager of the
whitespace before every token (and optionally with more changes inside
tokens).
Then, we run over all whitespace in the very end in original source
order, where we have all information available to correctly align
comments and escaped newlines.
The future direction is to pull more of the comment alignment
implementation that is now in the BreakableToken into the
WhitespaceManager.
This fixes a bug when aligning comments or escaped newlines in unwrapped
lines that are handled out of order:
#define A \
f({ \
g(); \
});
... now gets correctly layouted.

clang-format was a bit too aggressive when trying to keep labels and
values on the same line.
Before:
llvm::outs()
<< "aaaaaaaaaaaaaaaaaaa: " << aaaaaaaaaaaaa(
aaaaaaaaaaaaaaaaaaaaaaaaaaaa);
After:
llvm::outs() << "aaaaaaaaaaaaaaaaaaa: "
<< aaaaaaaaaaaaa(aaaaaaaaaaaaaaaaaaaaaaaaaaaa);

This only affects styles that prevent bin packing. There, a break after
a template declaration also forced a line break after the function name.
Before:
template <class SomeType, class SomeOtherType>
SomeType
SomeFunction(SomeType Type, SomeOtherType OtherType) {}
After:
template <class SomeType, class SomeOtherType>
SomeType SomeFunction(SomeType Type, SomeOtherType OtherType) {}
This fixes llvm.org/PR16072.

If clang-format is confronted with long and deeply nested lines (e.g.
complex static initializers or function calls), it can currently try too
hard to find the optimal solution and never finish. The reason is that
the memoization does not work effectively for deeply nested lines.
This patch removes an earlier workaround and instead opts for
accepting a non-optimal solution in rare cases. However, it only does
so only in cases where it would have to analyze an excessive number of
states (currently set to 10000 - the most complex line in Format.cpp
requires ~800 states) so this should not change the behavior in a
relevant way.

The crash is triggered by the newly added option (-analyzer-config report-in-main-source-file=true) introduced in r182058.
Note, ideally, we’d like to report the issue within the main source file here as well.
For now, just do not crash.

*that* easy...
Try a bit harder to disambiguate. This is mostly straightforward, but for
=-style initializers, we actually need to know where an expression ends:
[foo = bar baz]
is a message send, whereas
[foo = bar + baz]
is a lambda-introducer. Handle this by parsing the expression eagerly, and
replacing it with an annotation token. By chance, we use the *exact same*
parsing rules in both cases (except that we need to assume we're inside a
message send for the parse, to turn off various forms of inapplicable
error recovery).

common function. The C++1y contextual implicit conversion rules themselves are
not yet implemented, however.
This also fixes a subtle bug where template instantiation context notes were
dropped for diagnostics coming from conversions for integral constant
expressions -- we were implicitly slicing a SemaDiagnosticBuilder into a
DiagnosticBuilder when producing these diagnostics, and losing their context
notes in the process.

With this patch, clang-format will try to keep the cursor at the
original code position in editor integrations (implemented for emacs and
vim). This means, after formatting, clang-format will try to keep the
cursor on the same character of the same token.

attach, rather than merging all comments on the declaration chain. This gives a
more faithful dump, and has the side benefit of unbreaking uses of dump() from
within AST deserialization (where the redeclaration chain may not be sane).

This resolves the last of the PR14606 failures in the GDB 7.5 test
suite. (but there are still unresolved issues in the imported_decl case
- we need to implement optional/lazy decls for functions & variables
like we already do for types)
