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).

Summary:
The motivation for this was me wanting to make the validity of dwarf
DIERefs explicit (via llvm::Optional<DIERef>). This meant that the class
would no longer have a default constructor. As the DIERef was being
stored in a UniqueCStringMap, this meant that this container (like all
standard containers) needed to work with non-default-constructible types
too.
This part is achieved by removing the default constructors for the map
entry types, and providing appropriate comparison overloads so that we
can search for map entries without constructing a dummy entry. While
doing that, I took the opportunity to modernize the code, and add some
tests. Functions that were completely unused are deleted.
This required also some changes in the Symtab code, as it was default
constructing map entries, which was not impossible even though its
value type was default-constructible. Technically, these changes could
be avoided with some SFINAE on the entry type, but I felt that the code
is cleaner this way anyway.
