Summary: A *.cpp file header in LLDB (and in LLDB) should like this: ``` //===-- TestUtilities.cpp -------------------------------------------------===// ``` However in LLDB most of our source files have arbitrary changes to this format and these changes are spreading through LLDB as folks usually just use the existing source files as templates for their new files (most notably the unnecessary editor language indicator `-*- C++ -*-` is spreading and in every review someone is pointing out that this is wrong, resulting in people pointing out that this is done in the same way in other files). This patch removes most of these inconsistencies including the editor language indicators, all the different missing/additional '-' characters, files that center the file name, missing trailing `===//` (mostly caused by clang-format breaking the line).
