abc1892057 Removing LLVM_DELETED_FUNCTION, as MSVC 2012 was the last reason for requiring the macro. NFC; Clang edition.

29d39d54e7 clang-format: Correctly mark preprocessor lines in child blocks. 
This prevents contracting:
  auto lambda = []() {
    int a = 2
  #if A
            + 2
  #endif
        ;
  };

into:
  auto lambda = []() { int a = 2
  #if A + 2
  #endif ; };

Which is obviously BAD.

This fixes llvm.org/PR22496.

33381f5e0b clang-format: Format Objective-C try blocks like all the other try blocks. 
Before:

  @try {
    // ...
  }
  @finally {
    // ...
  }

Now:

  @try {
    // ...
  } @finally {
    // ...
  }

This is consistent with how we format C++ try blocks and SEH try blocks.
clang-format not doing this before was an implementation oversight.

This is dependent on BraceBreakingStyle.  The snippet above is with the
Attach style.  Style Stroustrip for example still results in the "Before:"
snippet, which makes sense since other blocks (try, else) break after '}' too.

30029c6b58 clang-format: Fix assert triggering on carriage returns.

fac2371be3 clang-format: Add support for SEH __try / __except / __finally blocks. 
This lets clang-format format

    __try {
    } __except(0) {
    }

and

    __try {
    } __finally {
    }

correctly. __try and __finally are keywords if `LangOpts.MicrosoftExt` is set,
so this turns this on.  This also enables a few other keywords, but it
shouldn't overly perturb regular clang-format operation.  __except is a
context-sensitive keyword, so `AdditionalKeywords` needs to be passed around to
a few more places.

Fixes PR22321.

d1c13736e0 clang-format: Fix another crasher caused by incomplete macro code. 
We did't properly mark all of an AnnotatedLine's children as finalized
and thus would reformat the same tokens in different branches of #if/#else
sequences leading to invalid replacements.
