Previously, before loading the REPL language-specific init file, lldb
checked the selected target language in which case it returned an unknown
language type with the REPL target.
Instead, the patch calls `Language::GetLanguagesSupportingREPLs` and
look for the first element of that set. In case lldb was not configured
with a REPL language, then, it will just stop sourcing the REPL init
file and fallback to the original logic (continuing with the default
init file).

Move the CommandObjectScript and CommandObjectRegexCommand under
Commands where all the other CommandObject implementations live.
Although neither implementations currently use the TableGen-generated
CommandOptions.inc, this move would have been necessary anyway if they
were to in the future.
This patch changes the command interpreter sourcing logic for the REPL
init file. Instead of looking for a arbitrary file name, it standardizes
the REPL init file name to match to following scheme:
`.lldbinit-<language>-repl`
This will make the naming more homogenous and the sourcing logic future-proof.

This patch adds the infrastructure to have language specific REPL init
files. It's the foundation work to a following patch that will introduce
Swift REPL init file.
When lldb is launched with the `--repl` option, it will look for a REPL
init file in the home directory and source it. This overrides the
default `~/.lldbinit`, which content might make the REPL behave
unexpectedly. If the REPL init file doesn't exists, lldb will fall back
to the default init file.

This is relanding D81001. The patch originally failed as on newer editline
versions it seems CC_REFRESH will move the cursor to the start of the line via
\r and then back to the original position. On older editline versions like
the one used by default on macOS, CC_REFRESH doesn't move the cursor at all.
As the patch changed the way we handle tab completion (previously we did
REDISPLAY but now we're doing CC_REFRESH), this caused a few completion tests
to receive this unexpected cursor movement in the output stream.
This patch updates those tests to also accept output that contains the specific
cursor movement commands (\r and then \x1b[XC). lldbpexpect.py received an
utility method for generating the cursor movement escape sequence.
Original summary:
I implemented autosuggestion if there is one possible suggestion.
I set the keybinds for every character. When a character is typed, Editline::TypedCharacter is called.
Then, autosuggestion part is displayed in gray, and you can actually input by typing C-k.
Editline::Autosuggest is a function for finding completion, and it is like Editline::TabCommand now, but I will add more features to it.
Testing does not work well in my environment, so I can't confirm that it goes well, sorry. I am dealing with it now.

This patch moves the `history` subcommand from the `command` to `session`
command. I think it makes more sense to have it there because as the `command`
usage suggests, it should be used to manage custom LLDB commands.
However, `history` is essentially tied to a debugging session and holds
all the commands (not specifically custom ones).
This also makes it more discoverable by adding an alias for it (mimicking
the shell builtin).

This patch introduce a new feature that allows the users to save their
debugging session's transcript (commands + outputs) to a file.
It differs from the reproducers since it doesn't require to capture a
session preemptively and replay the reproducer file in lldb.
The user can choose the save its session manually using the session save
command or automatically by setting the interpreter.save-session-on-quit
on their init file.
To do so, the patch adds a Stream object to the CommandInterpreter that
will hold the input command from the IOHandler and the CommandReturnObject
output and error. This way, that stream object accumulates passively all
the interactions throughout the session and will save them to disk on demand.
The user can specify a file path where the session's transcript will be
saved. However, it is optional, and when it is not provided, lldb will
create a temporary file name according to the session date and time.

SBTarget::AddModule currently handles the UUID parameter in a very
weird way: UUIDs with more than 16 bytes are trimmed to 16 bytes. On
the other hand, shorter-than-16-bytes UUIDs are completely ignored. In
this patch, we change the parsing code to handle UUIDs of arbitrary
size.
To support arbitrary size UUIDs in SBTarget::AddModule, this patch
changes UUID::SetFromStringRef to parse UUIDs of arbitrary length. We
subtly change the semantics of SetFromStringRef - SetFromStringRef now
only succeeds if the entire input is consumed to prevent some
prefix-parsing confusion. This is up for discussion, but I believe
this is more consistent - we always return false for invalid UUIDs
rather than sometimes truncating to a valid prefix. Also, all the
call-sites except the API and interpreter seem to expect to consume
the entire input.
This also adds tests for adding existing modules 4-, 16-, and 20-byte
build-ids. Finally, we took the liberty of testing the minidump
scenario we care about - removing placeholder module from minidump and
replacing it with the real module.

This patch introduces the `(-h|--host)` option to the `platform shell`
command. It allows the user to run shell commands from the host platform
(always available) without putting lldb in the background.
Since the default behaviour of `platform shell` is to run the command of
the selected platform, having such a choice can be quite handy when
debugging remote targets, for instances.
This patch also introduces a `shell` alias, to improve the command
discoverability and make it more convenient to use for the user.
