Fix some issues with whitespace in formatter.

Fix some issues with whitespace in formatter.

1) Insert a whitespace after the forward slash of a single line comment e.g:
//hello. -> // hello.

2) Remove whitespace above the first element in a container:
struct Hello {

  enum Something {
    BLAH,
  };
};


becomes:
struct Hello {
  enum Something {
    BLAH,
  };
};
