Because of the lack of this case, `[*ary,1,2,3,4,5,6]` was parsed into

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.

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.

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`.

to end with nd_else or nd_resq. Before this commit,

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.
