e19387e693 We can't let GetStackFrameCount get interrupted or it will give the
wrong answer. Plus, it's useful in some places to have a way to force
the full stack to be created even in the face of
interruption. Moreover, most of the time when you're just getting
frames, you don't need to know the number of frames in the stack to
start with. You just keep calling
Thread::GetStackFrameAtIndex(index++) and when you get a null
StackFrameSP back, you're done. That's also more amenable to
interruption if you are doing some work frame by frame.

So this patch makes GetStackFrameCount always return the full count,
suspending interruption. I also went through all the places that use
GetStackFrameCount to make sure that they really needed the full stack
walk. In many cases, they did not. For instance frame select -r 10 was
getting the number of frames just to check whether cur_frame_idx + 10
was within the stack. It's better in that case to see if that frame
exists first, since that doesn't force a full stack walk, and only
deal with walking off the end of the stack if it doesn't...

I also added a test for some of these behaviors.

04aa943be8 [lldb] Expose a const iterator for SymbolContextList
There are many situations where we'll iterate over a SymbolContextList
with the pattern:
```
SymbolContextList sc_list;
// Fill in sc_list here
for (auto i = 0; i < sc_list.GetSize(); i++) {
  SymbolContext sc;
  sc_list.GetSymbolAtContext(i, sc);

  // Do work with sc
}
```
Adding an iterator to iterate over the instances directly means we don't
have to do bounds checking or create a copy of every element of the
SymbolContextList.

808142876c [lldb][NFC] Fix all formatting errors in .cpp file headers
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).

CompileUnit is a complicated class. Having it be implicitly convertible

This patch replaces the inheritance by a simple member and an accessor
function. This avoid the need for casting in places where one needed to
force a CompileUnit to be treated as a FileSpec, and does not add much
verbosity elsewhere.

It also fixes a bug where we were wrongly comparing CompileUnit& and a
CompileUnit*, which compiled due to a combination of this inheritance
and the FileSpec*->FileSpec implicit constructor.

ae34ed2c0d [lldb][NFC] Remove WordComplete mode, make result array indexed from 0 and remove any undocumented/redundant return values
Summary:
We still have some leftovers of the old completion API in the internals of
LLDB that haven't been replaced by the new CompletionRequest. These leftovers
are:

* The return values (int/size_t) in all completion functions.
* Our result array that starts indexing at 1.
* `WordComplete` mode.

I didn't replace them back then because it's tricky to figure out what exactly they
are used for and the completion code is relatively untested. I finally got around
to writing more tests for the API and understanding the semantics, so I think it's
a good time to get rid of them.

A few words why those things should be removed/replaced:

* The return values are really cryptic, partly redundant and rarely documented.
  They are also completely ignored by Xcode, so whatever information they contain will end up
  breaking Xcode's completion mechanism. They are also partly impossible to even implement
  as we assign negative values special meaning and our completion API sometimes returns size_t.

  Completion functions are supposed to return -2 to rewrite the current line. We seem to use this
  in some untested code path to expand the history repeat character to the full command, but
  I haven't figured out why that doesn't work at the moment.
  Completion functions return -1 to 'insert the completion character', but that isn't implemented
  (even though we seem to activate this feature in LLDB sometimes).
  All positive values have to match the number of results. This is obviously just redundant information
  as the user can just look at the result list to get that information (which is what Xcode does).

* The result array that starts indexing at 1 is obviously unexpected. The first element of the array is
  reserved for the common prefix of all completions (e.g. "foobar" and "footar" -> "foo"). The idea is
  that we calculate this to make the life of the API caller easier, but obviously forcing people to have
  1-based indices is not helpful (or even worse, forces them to manually copy the results to make it
  0-based like Xcode has to do).

* The `WordComplete` mode indicates that LLDB should enter a space behind the completion. The
  idea is that we let the top-level API know that we just provided a full completion. Interestingly we
  `WordComplete` is just a single bool that somehow represents all N completions. And we always
  provide full completions in LLDB, so in theory it should always be true.
  The only use it currently serves is providing redundant information about whether we have a single
  definitive completion or not (which we already know from the number of results we get).

This patch essentially removes `WordComplete` mode and makes the result array indexed from 0.
It also removes all return values from all internal completion functions. The only non-redundant information
they contain is about rewriting the current line (which is broken), so that functionality was moved
to the CompletionRequest API. So you can now do `addCompletion("blub", "description", CompletionMode::RewriteLine)`
to do the same.

For the SB API we emulate the old behaviour by making the array indexed from 1 again with the common
prefix at index 0. I didn't keep the special negative return codes as we either never sent them before (e.g. -2) or we
didn't even implement them in the Editline handler (e.g. -1).

I tried to keep this patch minimal and I'm aware we can probably now even further simplify a bunch of related code,
but I would prefer doing this in follow-up NFC commits

I was going through some of the old bugs and came across PR21069 which I
was able to reproduce. The issue is that we match the regex `^foo`
against the `DW_AT_name` in the DWARF, which for our anonymous function
is indeed `foo`. However, when we get the function name from the symbol
context, the result is `(anonymous namespace)::foo()`. This throws off
completions, which assumes that it's appending to whatever is already
present on the input, resulting in a bogus
`b fooonymous\ namespace)::foo()`.

8b3af63b89 [NFC] Remove ASCII lines from comments
A lot of comments in LLDB are surrounded by an ASCII line to delimit the
begging and end of the comment.

Its use is not really consistent across the code base, sometimes the
lines are longer, sometimes they are shorter and sometimes they are
omitted. Furthermore, it looks kind of weird with the 80 column limit,
where the comment actually extends past the line, but not by much.
Furthermore, when /// is used for Doxygen comments, it looks
particularly odd. And when // is used, it incorrectly gives the
impression that it's actually a Doxygen comment.

I assume these lines were added to improve distinguishing between
comments and code. However, given that todays editors and IDEs do a
great job at highlighting comments, I think it's worth to drop this for
the sake of consistency. The alternative is fixing all the
inconsistencies, which would create a lot more churn.
