[CMake] Get rid of unconditional dependency to ClangDiagnosticCommon. Only clangBasic and clangASTMatchers need it.

a bit -- we're creating the UnwindPlan here, we can set the register set to
whatever is convenient for us, no need to handle different register sets.

A handful of small comment fixes I noticed while reading through the code.

 * When substituting a reference to a non-type template parameter pack where the
   corresponding argument is a pack expansion, transform into an expression
   which contains an unexpanded parameter pack rather than into an expression
   which contains a pack expansion. This causes the SubstNonTypeTemplateParmExpr
   to be inside the PackExpansionExpr, rather than outside, so the expression
   still looks like a pack expansion and can be deduced.

 * Teach MarkUsedTemplateParameters that we can deduce a reference to a template
   parameter if it's wrapped in a SubstNonTypeTemplateParmExpr (such nodes are
   added during alias template substitution).

Change emplace for vector and deque to create the temporary (when necessary) before any changes to the container are made.  Nikolay Ivchenkov deserves the credit for pushing this problem and the solution for it.

Remove some trivial copy ctors so the classes become trivially copyable and get the optimized SmallVector implementation.

-ftemplate-depth limit.  There are various ways to get an infinite (or merely
huge) stack of substitutions with no intervening instantiations. This is also
consistent with gcc's behavior.

multidimensional array of class type. Also, preserve zero-initialization when
evaluating an initializer list for an array, in case the initializers refer to
later elements (which have preceding zero-initialization).

Apply constexpr to the mutex constructor.  As a conforming extension, apply constexpr to the condition_variable constructor.  These are important because it enables the compiler to construct these types at compile time, even though the object will be non-const.  Since they are constructed at compile time, there is no chance of a data race before they are constructed.

For some reason GCC decided to call the feature rdrnd instead of rdrand,
which requires translating it for LLVM.

which will appear in the vtable as used, not just those ones which were
declared within the class itself. Fixes an issue reported as comment#3 in
PR12763 -- we sometimes assert in codegen if we try to emit a reference to a
function declaration which we've not marked as referenced. This also matches
gcc's observed behavior.

subtarget CPU descriptions and support new features of
MachineScheduler.

MachineModel has three categories of data:
1) Basic properties for coarse grained instruction cost model.
2) Scheduler Read/Write resources for simple per-opcode and operand cost model (TBD).
3) Instruction itineraties for detailed per-cycle reservation tables.

These will all live side-by-side. Any subtarget can use any
combination of them. Instruction itineraries will not change in the
near term. In the long run, I expect them to only be relevant for
in-order VLIW machines that have complex contraints and require a
precise scheduling/bundling model. Once itineraries are only actively
used by VLIW-ish targets, they could be replaced by something more
appropriate for those targets.

This tablegen backend rewrite sets things up for introducing
MachineModel type #2: per opcode/operand cost model.
