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.

to represent execution context [Feature #14038]
* vm_core.h (rb_thread_t): rb_thread_t::ec is now a pointer.
There are many code using `th` to represent execution context
(such as cfp, VM stack and so on). To access `ec`, they need to
use `th->ec->...` (adding one indirection) so that we need to
replace them by passing `ec` instead of `th`.

Return value of EXEC_TAG() is saved by "int state".
Instead of "int", use "enum ruby_tag_type". First EXEC_TAG()
value should be 0, so that define TAG_NONE (= 0) and use it.
Some code used "status" instead of "state". To make them clear,
rename them to state.
We can change variable name from "state" to "tag_state", but this
ticket doesn't contain it.

rb_autoload_str may be safer by preventing premature GC. It
can also be more efficient by passing a pre-frozen string that
can be deduped using rb_fstring. Common autoload callers (e.g.
rubygems, rdoc) already use string literals as the file
argument.
There seems to be no reason to expose rb_autoload_str to the
public C API since autoload is not performance-critical.
Applications may declare autoloads in Ruby code or via
rb_funcall; so merely deprecate rb_autoload without exposing
rb_autoload_str to new users.

How can a 'throw' happen while the current thread is reading a Ruby source file
from disk and parsing it? It can happen if another thread calls Thread#raise,
and passes an Exception object which responds to #exception, and the custom #exception
method calls Kernel#throw.
In practice, this is most likely to happen if you combine the use of autoload and
Timeout.timeout.
An extra check is required to avoid a segfault in this case.

All contents of previous rb_iseq_t is in rb_iseq_t::body.
Remove rb_iseq_t::self because rb_iseq_t is an object.
RubyVM::InstructionSequence is wrapper object points T_IMEMO/iseq.
So RubyVM::ISeq.of(something) method returns different wrapper
objects but they point the same T_IMEMO/iseq object.

iseq->xxx to iseq->body->xxx.
