fix https://github.com/ruby/irb/issues/308
This bug occurred when `dialog.width - calculate_width(s, true)` was negative.
When `dialog.width` is shorter than `old_dialog.width`, it calculates how much padding it has to do. However, there are cases where `s` is longer than `dialog.width`, as in the issue. In that case, `padding_space_with_escape_sequences` will crash.
Here, `old_dialog.width` is longer than `dialog.width`, so I changed the padding width to `old_dialog.width - dialog.width`.

The implementation of a local variable tables was represented as `ID*`,
but it was very hacky: the first element is not an ID but the size of
the table, and, the last element is (sometimes) a link to the next local
table only when the id tables are a linked list.
This change converts the hacky implementation to a normal struct.
This is the minimal correct objtostring implementation in YJIT.
For correctness, it is important that to_string not get called on strings or subclasses of string.
There is a new test for this behavior.
A follow up should implement an optimized version for other types as performed in `vm_objtostring`.

* `GC.measure_total_time = true` enables total time measurement (default: true)
* `GC.measure_total_time` returns current flag.
* `GC.total_time` returns measured total time in nano seconds.
* `GC.stat(:time)` (and Hash) returns measured total time in milli seconds.
This provides a significant speedup for symbol, true, false,
nil, and 0-9, class/module, and a small speedup in most other cases.
Speedups (using included benchmarks):
:symbol :: 60%
0-9 :: 50%
Class/Module :: 50%
nil/true/false :: 20%
integer :: 10%
[] :: 10%
"" :: 3%
One reason this approach is faster is it reduces the number of
VM instructions for each interpolated value.
Initial idea, approach, and benchmarks from Eric Wong. I applied
the same approach against the master branch, updating it to handle
the significant internal changes since this was first proposed 4
years ago (such as CALL_INFO/CALL_CACHE -> CALL_DATA). I also
expanded it to optimize true/false/nil/0-9/class/module, and added
handling of missing methods, refined methods, and RUBY_DEBUG.
This renames the tostring insn to anytostring, and adds an
objtostring insn that implements the optimization. This requires
making a few functions non-static, and adding some non-static
functions.
This disables 4 YJIT tests. Those tests should be reenabled after
YJIT optimizes the new objtostring insn.

We only need the cref when we have a cache miss so don't look it up until we
need it. This likely speeds up class variable writes in the interpreter but
also simplifies the jit code.

Followup to ruby/ruby#5137
Previously, each of these methods returned self, but it is
more useful to return arguments, to allow for simpler method
decorators, such as:
```ruby
cached private def foo; some_long_calculation; end
```
Where cached sets up caching for the method.
For each of these methods, the following behavior is used:
1) No arguments returns nil
2) Single argument is returned
3) Multiple arguments are returned as an array
The single argument case is really the case we are trying to
optimize for, for the same reason that def was changed to return
a symbol for the method.
Idea and initial patch from Herwin Quarantainenet.

* Refactor getclassvariable
We only need the cref when we have a cache miss so don't look it up until we
need it. This speeds up class variable reads in the interpreter but
also simplifies the jit code.
Benchmarks for master vs this branch (without yjit):

read a cvar 12.596M (± 1.7%) i/s - 63.781M in 5.064902s
```
After:
```
Warming up --------------------------------------
read a cvar 1.336M i/100ms

* Add --yjit-no-type-prop so we can test YJIT without type propagation
* Fix typo in command line option
* Leave just two test workflows enable for YJIT
An almost universal convention for gems is to expose `Namespace::VERSION`
which makes it mcuh easier when debugging etc.
Many gems extracted from ruby don't do this, even though it would be even more
useful because they ship with ruby, so it's less clear which version it is.

Instead of always using a new anonymous module for Kernel#load if
the wrap argument is not false/nil, use the given module if a module
is provided.
