parse.y: fix segv with Ripper#yydebug

	* parse.y (parser_token_value_print): in ripper, ID values are
	  wrapped in NODE_RIPPER at set_yylval_name(), so print the Symbol

d65f7458bc parse.y: remove coverage-related code fragments
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.

48de2ea5f9 range.c: prohibit (1..nil)
Now endless range can be created by either a literal `(1..)` or explicit
range creation `Range.new(1, nil)`.  [Bug #14845]

This change is intended for "early failure"; for example,
`(1..var).to_a` causes out of memory if `var` is inadvertently nil.

744b0bdb7b parse.y: Fix locations of none and mid-rule actions
When an empty rule or a mid-rule action is reduced,
`YYLLOC_DEFAULT` is called with the third parameter to be zero.
If we use `RUBY_SET_YYLLOC_OF_NONE` to set their locations,
sometimes the end position of NODE indicates a blank.
For example, `a.b ;` generates `NODE_CALL (line: 1, location: (1,0)-(1,4))*`,
whose end position indicates a blank.

This is because of the following reasons:

* `NODE_CALL` is created when `primary_value call_op operation2 opt_paren_args` is
  reduced to `method_call`.
* `opt_paren_args` is `none`.
* `yylex` is called and `lex.pbeg` moves before `none` is reduced, so
  the beginning position of `none` does not match with the end position of `operation2`.

To fix locations, use `YYRHSLOC(Rhs, 0)` in `YYLLOC_DEFAULT`
(0 "refers to the symbol just before the reduction").

By this change, the bottom of the location stack would be referenced,
so initialize the bottom with `RUBY_SET_YYLLOC_OF_NONE` in `%initial-action`.

687308cf0d explicit cast to void* required for %p
No automatic type promotion is expected for variadic arguments.
You have to do it by hand.

4dc5b6ff58 parse.y: relax literal in condition warnings
* parse.y (cond0): do not warn literal boolean (true and false) in
  condition expressions, as they are often used as infinite loops,
  deactivated code block, etc.

* parse.y (primary, new_args_tail, local_tbl): keep the order;
  allocate an empty imemo first then xmalloc, to get rid of
  potential memory leak when allocation imemo failed.

5afa84b028 parse.y: Fix locations of NODE_NIL in endless ranges.
* parse.y: Fix to start with the end of dots.

  e.g. The locations of the NODE_NIL is fixed:

  ```
  1..
  ```

  * Before

  ```
  NODE_NIL (line: 1, location: (1,0)-(1,3))
  ```

  * After

  ```
  NODE_NIL (line: 1, location: (1,3)-(1,3))
  ```

af0696782d gc.c (rb_imemo_alloc_new): split for each purpose
imemo_alloc is used for three purposes: auto-free pointer (alternative
of alloca), alloc_tmp_buffer, and heap allocation for bison.
To make it clear, this change introduces three functions:
rb_imemo_alloc_auto_free_pointer,
rb_imemo_alloc_auto_free_maybe_mark_buffer, and
rb_imemo_alloc_parser_heap.

58823392b4 gc.c (rb_imemo_alloc_new): improve the API interface
rb_imemo_alloc_new returns rb_imemo_alloc_t*, but took VALUEs, which is
inconsistent.  To make the intention clear, it now takes only a pointer
to the buffer.

Typical usages:

(1..).each {|n|...} # iterate forever from 1; identical to 1.step{...}
