bytesplice(index, length, str, str_index, str_length) -> string
bytesplice(range, str, str_range) -> string
In these forms, the content of +self+ is replaced by str.byteslice(str_index, str_length) or str.byteslice(str_range); however the substring of +str+ is not allocated as a new string.
In Feature #19314, we concluded that the return value of String#bytesplice
should be changed from the source string to the receiver, because the source
string is useless and confusing when extra arguments are added.
This change should be included in Ruby 3.2.1.
Some background for this refactor:
1. Through a RubyLex instance's lifetime, the context passed to its methods
should be the same.
Given that `Context` is only initialised in `Irb#initialize`,
this should be true.
2. When `RubyLex` is initialised, the context object should be accessible.
This is also true in all 3 of `RubyLex.new`'s invocations.
With the above observations, we should be able to store the context in `RubyLex`
as an instance variable. And doing so will make `RubyLex`'s instance methods
easier to use and maintain.

In Ruby 3.2 or later, a nested constant access like `Foo::Bar::Baz` is
compiled to one instruction by the optimization https://github.com/ruby/ruby/pull/6187
We try to spot which sub-node caues a NameError in question based on the
constant name. We will give up if the same constant name is accessed in
a nested access (`Foo::Foo`).

On the cfunc methods, if a splat argument is given, all array elements
are expanded on the VM stack and it can cause SystemStackError.
The idea to avoid it is making a hidden array to contain all parameters
and use this array as an argv.
This patch is reviesed version of https://github.com/ruby/ruby/pull/6816
The main change is all changes are closed around calling cfunc logic.

When the main object is frozen, `IRB` wraps a `SimpleDelegator` around it.
But because `SimpleDelegator` doesn't delegate private methods, methods like
`require_relative` or `const_get` would cause error, which are needed for
lazily loading commands.
This commit works around this limitation by avoiding those private method calls
when setting up command execution.
sequence) to check_multiline_prompt
(https://github.com/ruby/reline/pull/458)
* pass unmodified lines to check_multiline_prompt
* Add test to check that output modified by output_modifier_proc is not passed to prompt_proc
(https://github.com/ruby/irb/pull/504)
* Simplify `RubyLex#set_prompt`
It's optional argument is never used by any caller.
* Remove the optional `p` argument from `RubyLex#set_input`
The argument is only used in a test case, which can be easily replaced by
a block argument.

This failure only occurred on a ruby built with `DEFS=\"-DRGENGC_CHECK_MODE=2\""`
and only on a specific machine (Docker container) and difficult to reproduce,
so skip this failure to check other failures.
Previously, we did not update `cfp->sp` before calling the C function of
ISEQs marked with `Primitive.attr! "inline"` (leaf builtins). This
caused the GC to miss temporary values on the stack in case the function
allocates and triggers a GC run. Right now, there is only a few leaf
builtins in numeric.rb on Integer methods such as `Integer#~`. Since
these methods only allocate when operating on big numbers, we missed
this issue.
Fix by saving PC and SP before calling the functions -- our usual
protocol for calling C functions that may allocate on the GC heap.

The reference updating code for strings is not re-embedding strings
because the code is incorrectly wrapped inside of a
`if (STR_SHARED_P(obj))` clause. Shared strings can't be re-embedded
so this ends up being a no-op. This means that strings can be moved to a
large size pool during compaction, but won't be re-embedded, which would
waste the space.

Currently, IRB has 35 test cases for 10 non-debugging commands, with the
rest 10 commands untested. So in the long-term, it could have around 70
test cases for all existing commands.
With this number of test cases, I think it's easier to manage them by grouping
them in classes (by command).
trace_arg->id is the ID of the original method of an aliased method. If
the original method is removed, then the lookup will fail. We should use
trace_arg->called_id instead, which is the ID of the aliased method.
Fixes [Bug #19305]
Previously if any of the tests that move objects between size pools
failed to move anything, then the call to stats.dig would return `nil`
which would then cause assert_operator to error.
This should be a test Failure, rather than an Error so this commit uses
a default value of 0 if stats.dig fails to find a key.
Also refactor object movement tests to use stats.dig, rather than :[]
