Don't pin named structs defined in Ruby
[Bug #20311]
`rb_define_class_under` assumes it's called from C and that the
reference might be held in a C global variable, so it adds the
class to the VM root.
In the case of `Struct.new('Name')` it's wasteful and make
the struct immortal.
Make Struct memory leak test faster

It times out on some platform, so we can reduce iterations.
On my machine it completes in 250ms and RSS grows 8X.
Implements [Feature #19000]
This commit adds copy with changes functionality for `Data` objects
using a new method `Data#with`.
Since Data objects are immutable, the only way to change them is by
creating a copy. This PR adds a `with` method for `Data` class instances
that optionally takes keyword arguments.
If the `with` method is called with no arguments, the behaviour is the
same as the `Kernel#dup` method, i.e. a new shallow copy is created
with no field values changed.
However, if keyword arguments are supplied to the `with` method, then
the copy is created with the specified field values changed. For
example:
```ruby
Point = Data.define(:x, :y)
point = Point.new(x: 1, y: 2)
point.with(x: 3) # => #<data Point x: 3, y: 2>
```
Passing positional arguments to `with` or passing keyword arguments to
it that do not correspond to any of the members of the Data class will
raise an `ArgumentError`.

struct_ivar_get recently started using rb_class_superclass to
resolve super instead of RCLASS_SUPER. This change made
Qnil a possible case we need to return from within the
struct_ivar_get for loop.
rb_ary_tmp_new suggests that the array is temporary in some way, but
that's not true, it just creates an array that's hidden and not on the
transient heap. This commit renames it to rb_ary_hidden_new.
I used this regex:
([A-Za-z]+)\.html#(?:class|module)-[A-Za-z]+-label-([A-Za-z0-9\-\+]+)
And performed a global find & replace for this:
rdoc-ref:$1@$2
* As the "doc/" prefix is specified by the `--page-dir` option,
remove from the rdoc references.
* Refer to the original .rdoc instead of the converted .html.
* Warn Struct#initialize with only keyword args
A part of [Feature #16806]
* Do not warn if `keyword_init: false`
is explicitly specified
* Add a NEWS entry
* s/in/from/
* Make sure all fields are initialized
Adds a full discussion of #dig, along with links from Array, Hash, Struct, and OpenStruct.
CSV::Table and CSV::Row are over in ruby/csv. I'll get to them soon.
The art to the thing is to figure out how much (or how little) to say at each #dig.
Noticed that struct rb_builtin_function is a purely compile-time
constant. MJIT can eliminate some runtime calculations by statically
generate dedicated C code generator for each builtin functions.
