This fixes the mistake of r60722.
I used `rb_gc_writebarrier_remember` to notify to GC that the references
is changed. But the function just adds the object to the remember set
blindly. Ko1 told me that `RB_OBJ_WRITE` is suitable in this case.

The field has a flag to represent if it is a keyword argument (that has
no braces, e.g., `foo(k:1)`) or hash literal (that has braces, e.g.,
`foo({k:1})`).

`rb_code_location_t` has two integers, lineno and column, which point to
one location on a code. Now `rb_code_location_t` is used instead of
`VALUE nd_location`.

This magic number has two meanings depending upon the context:
* "required keyword argument (no name)" on NODE_LASGN (`def foo(x:)`)
* "rest argument (no name)" on NODE_MASGN and NODE_POSTARG
('a, b, * = ary` or `a, b, *, z = ary`)
To show this intention explicitly, two macros are introduced:
NODE_SPECIAL_REQUIRED_KEYWORD and NODE_SPECIAL_NO_NAME_REST.

When NODE_WHEN is compiled by iseq_compile_each0,
the node passed to compile_when is NODE_WHEN (not NODE_CASE).
So we can not handle the location of NODE_CASE of
case statements which don't have case expressions.
e.g. :
```
case; when 1; foo; when 2; bar; else baz; end
```
This commit adds NODE_CASE2, and compiles it by
iseq_compile_each0.
* compile.c (compile_case): Does not call COMPILE_ when
NODE_CASE does not have case expressions.
* compile.c (compile_case2): Compile NODE_CASE2 by compile_case2.
* compile.c (compile_when): Delete an obsoleted function.
* compile.c (iseq_compile_each0): Compile NODE_CASE2.
* ext/objspace/objspace.c (count_nodes): Add NODE_CASE2 case.
* node.c (dump_node, rb_gc_mark_node): Add NODE_CASE2 case.
* node.h (node_type): Add NODE_CASE2.
* node.h (NEW_CASE2): Add a macro which generates NODE_CASE2.
* parse.y: Generate NODE_CASE2 if case expressions don't exist.

This re-introduces r60485.
This reverts commit 5a176b75b1.

NODEs in AST are no longer objects managed by GC. This change will
remove the restriction imposed by the GC. For example, a NODE can use
more than five words (this is my primary purpose; we want to store the
position data for each NODE, for coverage library), or even a NODE can
have variable length (some kinds of NODEs have unused fields).
To do this, however, we need more work, since Ripper still uses T_NODE
objects managed by the GC.
The life time of NODEs is more obvious than other kinds of objects; they
are created at parsing, and they become disused immediately after
compilation. This change releases all NODEs by a few `xfree`s after
compilation, so performance will be improved a bit. In extreme example,
`eval("x=1;" * 10000000)` runs much faster (40 sec. -> 7.8 sec. on my
machine).
The most important part of this change is `ast_t` struct, which has
three contents: (1) NODE buffer (malloc'ed memory), (2) a reference to
the root NODE, and (3) an array that contains objects that must be
marked during parsing (such as literal objects). Some functions that
had received `NODE*` arguments, must now receive `ast_t*`.
* node.c, node.h: defines `ast_t` struct and related operations.
* gc.c, internal.h: defines `imemo_ast`.
* parse.y: makes `parser_params` struct have a reference to `ast_t`.
Instead of `rb_node_newnode`, use `rb_ast_newnode` to create a NODE.
* iseq.c, load.c, ruby.c, template/prelude.c.tmpl: modifies some
functions to handle `ast_t*` instead of `NODE*`.
* test/ruby/test_gc.rb: ad-hoc fix for a failed test. The test assumes
GC eden is increased at startup by NODE object creation. However,
this change now create no NODE object, so GC eden is not necessarily
increased.

A temporary NODE object was allocated to create iseq. Instead, this
patch allocates a dummy NODE as auto variable, and discard it soon.
This change is intended as a preparation to manage AST NODEs out of GC.

The magic number was used to mark NODE_ATTRASGN when its receiver is
self. But the hack was refactored at r46366. So the remaining code
fragments are no longer needed.
