Refactor DynTypedMatcher into a value type class, just like Matcher<T>.

Summary:
Refactor DynTypedMatcher into a value type class, just like Matcher<T>.
This simplifies its usage and removes the virtual hierarchy from Matcher<T>.
It also enables planned changes to replace MatcherInteface<T>.
Too many instantiaions of this class hierarchy has been causing Registry.cpp.o to bloat in size and number of symbols.

GCC does the same.

Make this test pass -verify.

Instead of using not, just drop the fastcall attribute which was causing
an warning:

Revert "Refactor DynTypedMatcher into a value type class, just like Matcher<T>."

llvm::Optional<DynTypedMatcher>.

Sema: Do not allow template declarations inside local classes

Summary:
Enforce the rule in C++11 [temp.mem]p2 that local classes cannot have
member templates.

This fixes PR16947.

N.B.  C++14 has slightly different wording to afford generic lambdas
declared inside of functions.

Fun fact:  Some formulations of local classes with member templates
would cause clang to crash during Itanium mangling, such as the
following:

void outer_mem() {
  struct Inner {
    template <typename = void>
    struct InnerTemplateClass {
      static void itc_mem() {}
    };
  };
  Inner::InnerTemplateClass<>::itc_mem();
}

Allow a header to be part of multiple modules.

This patch changes two things:

a) Allow a header to be part of multiple modules. The reasoning is that
in existing codebases that have a module-like build system, the same
headers might be used in several build targets. Simple reasons might be
that they defined different classes that are declared in the same
header. Supporting a header as a part of multiple modules will make the
transistion easier for those cases. A later step in clang can then
determine whether the two modules are actually compatible and can be
merged and error out appropriately. The later check is similar to what
needs to be done for template specializations anyway.

b) Allow modules to be stored in a directory tree separate from the
headers they describe.

Remove incorrect assert.

If we run into the second preprocessor branch chain, the first branch
chain might have already set the maximum branch count on that level to
something > 0.

This patch causes clang to reject alias attributes that point to undefined
names. For example, with this patch we now reject

void f1(void) __attribute__((alias("g1")));

This patch is implemented in CodeGen. It is quiet a bit simpler and more
compatible with gcc than implementing it in Sema. The downside is that the
errors only fire during -emit-llvm.

Revert "This patch causes clang to reject alias attributes that point to undefined names. For example, with this patch we now reject"

This reverts commit r193161.

It broke

void foo() __attribute__((alias("bar")));
void bar() {}
void zed() __attribute__((alias("foo")));

Looks like we have to fix pr17639 first :-(

clang-format: Improve formatting of ObjC array literals.

Before:
  NSArray *arguments =
      @[ kind == kUserTicket ? @"--user-store" : @"--system-store",
         @"--print-tickets", @"--productid", @"com.google.Chrome" ];
After:
  NSArray *arguments = @[

      @"--print-tickets",
      @"--productid",
      @"com.google.Chrome"
