clang-format: Fix indentation relative to unary expressions.

This should be done, only if we are still in the unary expression's
scope.

Before:
  bool aaaa = !aaaaaaaa(  // break
                   aaaaaaaaaaa);
  *aaaaaa = aaaaaaa( // break
       aaaaaaaaaaaaaaaa);

After:
  bool aaaa = !aaaaaaaa(  // break
                   aaaaaaaaaaa); // <- (unchanged)
  *aaaaaa = aaaaaaa( // break
      aaaaaaaaaaaaaaaa); // <- (no longer indented relative to "*")

Respect -Wnewline-eof even in C++11 mode.

If the user has requested this warning, we should emit it, even if it's not
an extension in the current language mode. However, being an extension is
more important, so prefer the pedantic warning or the pedantic-compatibility
warning if those are enabled.

Comment parsing: fix a bug where a line with whitespace between two paragraphs
would cause us to concatenate these paragraphs into a single one.

The no-op whitespace churn in test/Index test happened because these tests
don't use the correct approach for testing and are more strict than required
for they are testing.

CMake: Don't look for llvm-tblgen when building outside LLVM tree

Previously, the CMake build would look for llvm-tblgen to determine
if a directory is an LLVM build or install directory. Since we don't
want to include llvm-tblgen in the install, look for llvm-config instead,
and use that to find llvm-tblgen.

Consumed analysis: change class name in test cases.

The name of a class used in the testing files was updated to actually
be descriptive.  Patch by chris.wailes@gmail.com.

Driver::IsUsingLTO() no longer return true when seeing -emit-llvm.

One step toward differentiating following two commands:
   clang -O3 -flto a.c -c, and 
   clang -O3 -emit-llvm a.c

Thanks many awesome folks for clarifying things.

Don't imply -flto with -O4.

We now saturate at -O3.

Add note about following two commands are no longer equivalent.
 - "clang -O3 -flto a.c -c", and 
 - "clang -emit-llvm a.c -c" 

Thank Rafael for tips.

DebugInfo: Emit info for constant expressions in template arguments

Summary:
This allows us to handle the general case where a non-type template
argument evaluates to a constant expression which isn't integral or a
declaration.

This fixes PR16939.
