Daniel Jasper 11a0ac66e1 clang-format: Revamp nested block formatting. 
This fixed llvm.org/PR21804 and hopefully a few other strange cases.

Before:
    if (blah_blah(whatever, whatever, [] {
      doo_dah();
      doo_dah();
    })) {
    }
    }

After:
    if (blah_blah(whatever, whatever, [] {
          doo_dah();
          doo_dah();
        })) {
    }
    }

                      > ccccccccccccccccccccccccccccccccccccccccc;

Not particularly pretty, but can probably help to uncover bugs. And if this
bugs somebody, parentheses can help.

With AllowShortCaseLabelsOnASingleLine set to true:
This gets now left unchanged:

Nico Weber 34272657de clang-format: Format extern "C" blocks like namespace blocks. 
namespace blocks act as if KeepEmptyLinesAtTheStartOfBlocks is always true,
and aren't collapsed to a single line even if they would fit. Do the same
for extern "C" blocks.

Before,

  extern "C" {

  void ExternCFunction();

  }

was collapsed into `extern "C" { void ExternCFunction(); }`. Now it stays like
it was.

Fixes http://crbug.com/432640 and part of PR21419.
