The current `next` pre-command workaround on IRB source stepping
moves the location by 1 extra line. A better way is to make `debug`
skip IRB frames completely, which is what this commit does.
It also fixes the step command's test. The `|` in regexp was not escaped
so it was always incorrectly matched.

In the long-term, we want to align with `Pry`, `byebug` and `debug` to
use the `help` command to list all commands, which is what `show_cmds`
currently does. And `show_doc` will be the command to look up Ruby APIs.
By aliasing `show_doc` to the current `help` now, users will have time
to get use to it.

* Handle file loading commands' argument error gracefully
Currently, if users don't provide an argument to `source`,
`irb_load`, and `irb_require`, IRB raises `ArgumentError` with full
stacktrace. This is confusing because it looks similar to when IRB has
internal issues. The message also isn't helpful on helping users avoid
the error.
So in this commit, I add a new `CommandArgumentError` for commands to
raise explicitly when users' input doesn't satisfy a command's argument
requirement.
* Gracefully handle `fg` command's argument requirement
Previously, when we froze an object, we froze
`RCLASS_ORIGIN(object.singleton_class)`, which didn't freeze
`object.singleton_class` when it has some prepended modules.
Origin iclass are internal objects and users can't interact with
them through Kernel#freeze?, Kernel#freeze, or any mutation method
that checks the frozen status. So we shouldn't touch the origin
iclasses when the frozen status should be visible.
[Bug #19169]
I see several arguments in doing so.
First they use a non trivial amount of memory, so for various memory
profiling/mapping tools it is relevant to have visibility of the space
occupied by shapes.
Then, some pathological code can create a tons of shape, so it is
valuable to have a way to have a way to observe shapes without having
to compile Ruby with `SHAPE_DEBUG=1`.
And additionally it's likely much faster to dump then this way than
to use `RubyVM::Shape`.
There are however a few open questions:
- Shapes can't respect the `since:` argument. Not sure what to do when
it is provided. Would probably make sense to not dump them.
- Maybe it would make more sense to have a separate `ObjectSpace.dump_shapes`?
- Maybe instead `dump_all` should take a `shapes: false` argument?
Additionally, `ObjectSpace.dump_shapes` is added for the use case of
debugging the evolution of the shape tree.
Cases like this:
```ruby
obj = Object.new
loop do
obj.instance_variable_set(:@foo, 1)
obj.remove_instance_variable(:@foo)
end
```
can cause us to use many more shapes than we want (and even run out).
This commit changes the code such that when an instance variable is
removed, we'll walk up the shape tree, find the shape, then rebuild any
child nodes that happened to be below the "targetted for removal" IV.
This also requires moving any instance variables so that indexes derived
from the shape tree will work correctly.

The change in the Unicode emoji file header took place at
version 14.0.0, but is needed only from version 15.0.0
because in version 14.0.0, another check is still active.
`IRB_USE_AUTOCOMPLETE=false`
(https://github.com/ruby/irb/pull/469)
* Allow using IRB_USE_AUTOCOMPLETE=false to disable autocompletion
Currently, the only 2 ways to disable autocompletion are:
1. Create `.irbrc` and set `IRB.conf[:USE_AUTOCOMPLETE] = false`
2. Add the `--noautocomplete` flag when using the `irb` executable
Both of them are less convenient than setting a env var and are
lesser known to devs.
And given the number of problems the autocompletion has (see #445), I
think we should allow disabling it with a simple `IRB_USE_AUTOCOMPLETE=false`.
* Mention some env var configs in the README
(https://github.com/ruby/did_you_mean/pull/180)
* Do not suggest #name= for #name and vice versa
* Avoid allocating unnecessary MatchData

These APIs/configs are not approved by the Ruby core, so they can't be
released to the public. This means having them in the codebase will
block other fixes/features from being released as well.
So this commit removes those exposed interfaces to unblock the release.
Hopefully when https://bugs.ruby-lang.org/issues/18996 is approved we
can re-implement better APIs.

If there is a compilation error, is_entries may not be allocated, but
ic_size could be greater than 0. If we don't have a buffer to iterate
over, just return early. Otherwise GC could segv
[Bug #19173]
UnboundMethod records caller's class, like `D` or `E` on the
following case:
```ruby
class C
def foo = :foo
end
class D < C
end
class E < C
end
d = D.instance_method(:foo)
e = E.instance_method(:foo)
```
But `d` and `e` only refers `C#foo` so that UnboundMethod doesn't
record `D` or `E`. This behavior changes the following methods:
* `UnboundMethod#inspect` (doesn't show caller's class)
* `UnboundMethod#==` (`d == e` for example)
fix https://bugs.ruby-lang.org/issues/18798
Previously, the frozen check happened on `RCLASS_ORIGIN(self)`, which
can return an iclass. The frozen check is supposed to respond to objects
that users can call methods on while iclasses are hidden from users.
Other mutation methods like Module#{define_method,alias_method,public}
don't do this. Check frozen status on the module itself.
Fixes [Bug #19164] and [Bug #19166].
