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`.
* vm_core.h (GET_EC()): introduced to access current ec. Also
remove `ruby_current_thread` global variable.
* cont.c (rb_context_t): introduce rb_context_t::thread_ptr instead of
rb_context_t::thread_value.
* cont.c (ec_set_vm_stack): added to update vm_stack explicitly.
* cont.c (ec_switch): added to switch ec explicitly.
* cont.c (rb_fiber_close): added to terminate fibers explicitly.

imemo_alloc provides a memory buffer whose contents are marked by GC.
C code can access imemo_alloc buffer freely, so imemo_alloc must be
considered writebarrier-unprotected. But T_IMEMO is writebarrier-
protected by default, which caused a GC bug.

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.

* vm_core.h: rename absolute_path to realpath because it is expected name.
external APIs (#absolute_path methods) are remained.
* vm_core.h: remove rb_iseq_location_struct::path and
rb_iseq_location_struct::absolute_path and introduce pathobj.
if given path equals to given absolute_path (and most of case
it is true), pathobj is simply given path String. If it is not same,
pathobj is Array and pathobj[0] is path and pathobj[1] is realpath.
This size optimization reduce 8 bytes and
sizeof(struct rb_iseq_constant_body) is 200 bytes -> 192 bytes
on 64bit CPU.
To support this change, the following functions are introduced:
* pathobj_path() (defined in vm_core.h)
* pathobj_realpath() (ditto)
* rb_iseq_path() (decl. in vm_core.h)
* rb_iseq_realpath() (ditto)
* rb_iseq_pathobj_new() (ditto)
* rb_iseq_pathobj_set() (ditto)
* vm_core.h (rb_binding_t): use pathobj instead of path. If binding
is given at eval methods, realpath (absolute_path) was caller's
realpath. However, they should use binding's realpath.
