std::set<std::string>, and use pretty range algos where we can.

Small sizes were arbitrarily chosen.

Would be NFC except we now also use a different uniquing structure so
that we don't get spurious conflicts if you ask for both an NSString

Teach Sema to check the aligned attribute attached to variable

When constructing a temporary object region, which represents the result of
MaterializeTemporaryExpr, track down the sub-expression for which the temporary
is necessary with a trick similar to the approach used in CodeGen, namely
by using Expr::skipRValueSubobjectAdjustments().

Then, create the temporary object region with type of that sub-expression.
That type would propagate further in a path-sensitive manner.

During destruction of lifetime-extened temporaries, consult the type of
the temporary object region, rather than the type of the lifetime-extending
variable, in order to call the correct destructor (fixes pr17001) and,
at least, not to crash by trying to call a destructor of a plain type
(fixes pr19539).

- Fix the bug with transition handling in ExprInspectionChecker's
  checkDeadSymbols implementation.

- Test this bug by adding a new function clang_analyzer_numTimesReached() to
  catch number of passes through the code, which should be handy for testing
  against unintended state splits.

- Add two more functions should help debugging issues quickly without running
  the debugger or dumping exploded graphs - clang_analyzer_dump() which dump()s
  an SVal argument to a warning message, and clang_analyzer_printState(), which
  dump()s the current program state to stderr.

Other AST consumers can deserialize interesting decls that we might
codegen, but they won't make it to the final object file and can trigger
assertions in debug information generation after finalization.

specifications in this mode in C++17, since they're part of the function type,
so check and diagnose them like we would if exceptions were enabled.

Otherwise MSVC and clang-cl will see "extern inline" after merging

Avoid using shortcut for const qualified non-constant address space
aggregate variables while generating them on the stack such that
the alloca object is used instead of a global variable containing
initializer.

Specifically, if the RHS of a comma is a complex binary expression and
spans multiple lines, insert a line break before it. This usually is
often more readable compared to producing a hanging indent. See changes
in FormatTest.cpp for examples.
