The fields of imemo_alloc were accessed via RNODE() cast, since the
imemo was NODE_ALLOCA traditionally. This was refactored at r60239,
so now the fields should be accessed as imemo_alloc. This prevented
change of NODE structure.
Yuichiro Kaneko pointed out this inconsistency. Thanks!

Just refactoring.
NODE_STRTERM and NODE_HEREDOC are not an internal node of AST, but a
temporary storage for managing termination of string literals and
heredocs. Instead of NODE abuse, I want to use imemo for the storage
in order to avoid (my) confusion.

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.

* 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`.

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.

external APIs (#absolute_path methods) are remained.
* vm_core.h: remove rb_iseq_location_struct::path and

pathobj is Array and pathobj[0] is path and pathobj[1] is realpath.

Introduce new environement variable
GC_HEAP_FREE_SLOTS_GOAL_RATIO (goal_ratio) to calculate the ratio
of additional memory.
Before this change, we add pages with the following formula
(when free_slots < total_pages * RUBY_GC_HEAP_FREE_SLOTS_MIN_RATIO):
next_pages = total_pages * RUBY_GC_HEAP_GROWTH_FACTOR
This addition can allocate too much.
With this change, we increase pages to satisfy the following formula:
next_free_slots = next_total_slots * goal_ratio
where
next_free_slots = free_slots + adding_slots
next_total_slots = total_slots + adding_slots.
If you want to prepare many free slots, increase this ratio.
If this variable is 0, then simply multiply
RUBY_GC_HEAP_GROWTH_FACTOR.
* gc.c (get_envparam_double): enable to accept 0.

Before this change, heap_pages_min_slots are calculated at the
beggining sweeping phase. And this value is used at the end of
*next* marking phase.
To simplify it, we use this value at the end of this marking phase.
It means that we don't need to store this value as global state.
Also heap_pages_max_slots is calculated at the begging of sweeping
phase and used at the end of sweeping phase.
To simplify this logic, we introduced new global value
heap_pages_freeable_pages it means extra pages count we can free.
gc_sweep_step() checks this value and moves empty pages to tomb_heap
not more than this value.
Because of this fix, heap_pages_swept_slots is no longer needed.

because there is a same name (no related) function gc_stat().
Also gc_stat_* are renamed to gc_mode_*,
gc_stat_transition() to gc_mode_transition(),
rb_objspace:🎏:stat is renamed to rb_objspace:🎏:mode.
Change rb_objspace:🎏:mode from 2 bits to 3 bits because VC++
returns negative enum value with 2 bits.
* gc.c (gc_mode): add a macro to access rb_objspace:🎏:mode
with verification code (verification is enabled only on
RGENGC_CHECK_MODE > 0).
* gc.c (gc_mode_set): same macro for setter.

a page).

whether a page is in a tomb or not. Instead of this field,
heap_page:🎏:in_tomb (1 bit field) is added.
Also type of heap_page::(total|free|final)_slots are changed from
int to short. 2B is enough for them.
