Remove old -fdiagnostics-show-name option

This had no effect since the feature was removed in r150612.

I actually miss this option, maybe we can bring it back some day.

clang-format: Be more conservative about braced list column layout.

Specifically disable it for nested braced lists as it commonly can look
really weird. Eventually, we'll want to become smarter and format some of
the nested lists better.

Before:
  SomeStruct my_struct_array = {
    { aaaaaa,     aaaaaaaa,   aaaaaaaaaa, aaaaaaaaa, aaaaaaaaa,
      aaaaaaaaaa, aaaaaaaaaa, aaaaaaa,    aaa },
    { aaaa, aaaa, aaaa, aaaa, aaaa, aaaa, aaaa, aaa },
    { aaaaaaaaaaaaaaaaa, aaaaaaaaaaaaaaaaa, aaaaaaaaaaaaaaaaaaaaaaaa,
      aaaaaaaaaaaa,      a,                 aaaaaaaaaa,
      aaaaaaaaa,         aaa },
  };

After:
  SomeStruct my_struct_array = {
    { aaaaaa, aaaaaaaa, aaaaaaaaaa, aaaaaaaaa, aaaaaaaaa, aaaaaaaaaa,
      aaaaaaaaaaaa, aaaaaaa, aaa },
    { aaaa, aaaa, aaaa, aaaa, aaaa, aaaa, aaaa, aaa },
    { aaaaaaaaaaaaaaaaa, aaaaaaaaaaaaaaaaa, aaaaaaaaaaaaaaaaaaaaaaaa,
      aaaaaaaaaaaa, a, aaaaaaaaaa, aaaaaaaaa, aaa },
  };

Output destructors and constructors in a more natural order.

With this patch we output the in the order
C2
C1

D2
D1
D0

Which means that a destructor or constructor that call another is output after
the callee. This is a bit easier to read IHMO and a tiny bit more efficient
as we don't put a decl in DeferredDeclsToEmit.
