and NODE_ZARRAY to NODE_ZLIST.
NODE_ARRAY is used not only by an Array literal, but also the contents
of Hash literals, method call arguments, dynamic string literals, etc.
In addition, the structure of NODE_ARRAY is a linked list, not an array.
This is very confusing, so I believe `NODE_LIST` is a better name.
I guess those AST node were actually used for something, so we'd better
not touch them. Instead this commit just puts the tmpbuffer inside a
different internal struct so that we can mark them.
This commit adds two buckets for allocating NODE structs, then allocates
"markable" NODE objects from one bucket. The reason to do this is so
when the AST mark function scans nodes for VALUE objects to mark, we
only scan NODE objects that we know to reference VALUE objects. If we
*did not* divide the objects, then the mark function spends too much
time scanning objects that don't contain any references.
This syntax means the method should be treated as a method that
uses keyword arguments, but no specific keyword arguments are
supported, and therefore calling the method with keyword arguments
will raise an ArgumentError. It is still allowed to double splat
an empty hash when calling the method, as that does not pass
any keyword arguments.
`(ID)1` was assigned to NODE_ARGS#rest_arg for `{|x,| }`.
This change removes the magic number by introducing an explicit macro
variable for it: NODE_SPECIAL_EXCESSED_COMMA.
NODE_HASH#nd_brace is a flag that is 1 for `foo({ k: 1 })` and 0 for
`foo(k: 1)`.
nd_alen had been abused for the flag (and the implementation is
completely the same), but an explicit name is better to read.

The code fragments that initializes coverage data were scattered into
both parse.y and compile.c. parse.y allocated a coverage data, and
compile.c initialize the data.
To remove this cross-cutting concern, this change moves the allocation
from "coverage" function of parse.y to "rb_iseq_new_top" of iseq.c.
For the sake, parse.y just counts the line number of the original source
code, and the number is passed via rb_ast_body_t.

If a function declarator includes no parameter list, that doesn't
mean the function takes zero parameter. rb_ast_new here does take
zero parameter, so it should be explicitly prototypes as (void).

NODE_FOR was used both for "for"-statement itself and for
multi-assignment of for-statement (for x, y, in...end).
This change separates the two purposes, NODE_FOR for the former, and
newly introduced NODE_FOR_MASGN for the latter.

In parse.y many functions were suffixed "_gen" and had companion macros
to pass struct parser_params implicitly, which made parse.c bigger and
more obscure.
This change expands and removes almost all "*_gen" macros. This
requires explicit passing of struct parser_params, i.e., we need to
write "foo(p, ..)" instead of "foo(..)". However, it is just extra
three letters. I believe that this is easier to understand.

Because the name "code_range" is ambiguous with encoding's.
Abbreviations ("crange", and "cr") are also renamed to "loc".
The traditional "code_location" (a pair of lineno and column) is
renamed to "code_position". Abbreviations are also renamed
(first_loc to beg_pos, and last_loc to end_pos).

"loc" was ambiguous; it might refer both a location and a code range.
This change uses "loc" for a location, and "crange" or "cr" for a code
range.
A location (abbr. loc) is a point in a program and consists of line
number and column number. A code range (abbr. crange and cr) is a range
within a program and consists of a pair of locations which is the first
and the last.

complexity.

NODE_PRELUDE contains a `BEGIN` node, a main node, and compile_option.
This node is assumed that it must be located immediately under the root
NODE_SCOPE, but this strange assumption is not so good, IMO.
This change removes the assumtion; it integrates the former two nodes by
block_append, and moves compile_option into rb_ast_body_t.

r60655 changed the usage of bison by defining a customized YYLTYPE,
which seemed to cause a random stall at rb_thread_terminate_all.
Kazuki Tsujimoto investigated the issue and pointed out the commit that
caused it. Thanks!

rb_code_range_t has two t_code_location_t, i.e., the first and last
locations.
This is used for YYLTYPE, tracked locations of bison, and will be also
used for representing the "range", the first and the last locations of
each NODE. Currently, each NODE keeps only the first location, though.
