Jim Ingham bc0a9a17a4 Add an option (-y) to "break set" and "source list" that uses the same
file:line:column form that we use to print out locations.  Since we
print them this way it makes sense we also accept that form.

Gongyu Deng 7c89297cf7 Correct the argument list of command breakpoint read
Summary: Command `breakpoint read` should not accept breakpoint ids as
arguments, and in fact, it is not implemented to deal with breakpoint id
arguments either. So this patch is to correct the argument list of this
command so that the help text won't misguide users.

Raphael Isemann aaf68cd9ce [lldb] Warn the user about starting the --func-regex parameter with an asterisk
Summary:
Sometimes users think that setting a function regex for all function that contain the word 'needle' in their
name looks like this: `*needle*`. However, LLDB only searches the function name and doesn't fully match
it against the regex, so the leading and trailing '*' operators don't do anything and actually just cause the
regex engine to reject the regular expression with "repetition-operator operand invalid".

This patch makes this a bit more obvious to the user by printing a warning that a leading '*' before this
regular expression here doesn't have any purpose (and will cause an error). This doesn't attempt to detect
a case where there is only a trailing '*' as that would involve parsing the regex and it seems the most
common way to end up in this situation is by doing `rbreak *needle*`.

Raphael Isemann b58af8d254 [lldb] Improve error message when --func-regex parameter for the breakpoint command is invalid
Summary:
Currently the breakpoint command is prompting the user to file a bug report if the provided regex is invalid:
```
(lldb) rbreak *foo
error: Function name regular expression could not be compiled: "Inconvertible error value. An error has occurred that could not be converted to a known std::error_code. Please file a bug. repetition-operator operand invalid"
```

The reason is simply that we are using the wrong StringError constructor (the one with the error code as the first parameter
is also printing the string version of the error code, and the inconvertible error code is just an invalid place holder code with
that description). Switching the StringError constructor parameters will only print the error message we get from the regex
engine when we convert the error into a string.

I checked the rest of the code base and I couldn't find the same issue anywhere else.

Fixes rdar://62233561

Benjamin Kramer adcd026838 Make llvm::StringRef to std::string conversions explicit.
This is how it should've been and brings it more in line with
std::string_view. There should be no functional change here.

This is mostly mechanical from a custom clang-tidy check, with a lot of
manual fixups. It uncovers a lot of minor inefficiencies.

This doesn't actually modify StringRef yet, I'll do that in a follow-up.

Raphael Isemann 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).

We were incorrectly parsing the -C argument to breakpoint set as the

breakpoint command. This fixes that by renaming the option to -u, adding
it to help, and adding a test case.

Jim Ingham 738af7a624 Add the ability to pass extra args to a Python breakpoint callback.
For example, it is pretty easy to write a breakpoint command that implements "stop when my caller is Foo", and
    it is pretty easy to write a breakpoint command that implements "stop when my caller is Bar". But there's no
    way to write a generic "stop when my caller is..." function, and then specify the caller when you add the
    command to a breakpoint.

    With this patch, you can pass this data in a SBStructuredData dictionary. That will get stored in
    the PythonCommandBaton for the breakpoint, and passed to the implementation function (if it has the right
    signature) when the breakpoint is hit. Then in lldb, you can say:

    (lldb) break com add -F caller_is -k caller_name -v Foo

    More generally this will allow us to write reusable Python breakpoint commands.

Raphael Isemann 0d9a201e26 [lldb][NFC] Remove ArgEntry::ref member
The StringRef should always be identical to the C string, so we
might as well just create the StringRef from the C-string. This
might be slightly slower until we implement the storage of ArgEntry
with a string instead of a std::unique_ptr<char[]>. Until then we
have to do the additional strlen on the C string to construct the
StringRef.

Raphael Isemann 36162014c4 [lldb][NFC] Remove dead code that is supposed to handle invalid command options
Summary:
We currently have a bunch of code that is supposed to handle invalid command options, but
all this code is unreachable because invalid options are already handled in `Options::Parse`.
The only way we can reach this code is when we declare but then not implement an option
(which will be made impossible with D65386, which is also when we can completely remove
the `default` cases).

This patch replaces all this code with `llvm_unreachable` to make clear this is dead code
that can't be reached.

Jonas Devlieghere 3af3f1e8e2 [Utility] Reimplement RegularExpression on top of llvm::Regex
Originally I wanted to remove the RegularExpression class in Utility and
replace it with llvm::Regex. However, during that transition I noticed
that there are several places where need the regular expression string.
So instead I propose to keep the RegularExpression class and make it a
thin wrapper around llvm::Regex.

This patch also removes the workaround for empty regular expressions.
The result is that we are now (more or less) POSIX conformant.

Raphael Isemann bd68a052f2 [lldb] Also include the array definition in CommandOptions.inc
Summary:
Right now our CommandOptions.inc only generates the initializer for the options list but
not the array declaration boilerplate around it. As the array definition is identical for all arrays,
we might as well also let the CommandOptions.inc generate it alongside the initializers.

This patch will also allow us to generate additional declarations related to that option list in
the future (e.g. a enum class representing the specific options which would make our
handling code less prone).

This patch also fixes a few option tables that didn't follow our naming style.
