This magic number has two meanings depending upon the context:
* "required keyword argument (no name)" on NODE_LASGN (`def foo(x:)`)
* "rest argument (no name)" on NODE_MASGN and NODE_POSTARG
('a, b, * = ary` or `a, b, *, z = ary`)
To show this intention explicitly, two macros are introduced:
NODE_SPECIAL_REQUIRED_KEYWORD and NODE_SPECIAL_NO_NAME_REST.

* compile.c (setup_args): In this function,
an argument of nd_line is argn except this line.
And argn is a pointer of NODE. So I think this
is a typo.

Now, casting NODE to VALUE is not recommended. This change requires an
explicit cast from VALUE to NODE to use the NODE utility functions such
as `nd_type`.

When NODE_WHEN is compiled by iseq_compile_each0,
the node passed to compile_when is NODE_WHEN (not NODE_CASE).
So we can not handle the location of NODE_CASE of
case statements which don't have case expressions.
e.g. :
```
case; when 1; foo; when 2; bar; else baz; end
```
This commit adds NODE_CASE2, and compiles it by
iseq_compile_each0.
* compile.c (compile_case): Does not call COMPILE_ when
NODE_CASE does not have case expressions.
* compile.c (compile_case2): Compile NODE_CASE2 by compile_case2.
* compile.c (compile_when): Delete an obsoleted function.
* compile.c (iseq_compile_each0): Compile NODE_CASE2.
* ext/objspace/objspace.c (count_nodes): Add NODE_CASE2 case.
* node.c (dump_node, rb_gc_mark_node): Add NODE_CASE2 case.
* node.h (node_type): Add NODE_CASE2.

* compile.c (compile_if, compile_case, compile_loop, iseq_compile_each0):
Use nd_lineno of nodes for branch coverages.
nd_lineno is not adjusted line number of nodes.
Sometimes nd_line is adjusted by fixpos. These
adjustments lead to confusing result.
For example, lineno of NODE_IF is 1, but
line is 2 (line number is one-based).

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.

[Feature #14045]
* insns.def (getblockparam, setblockparam): add special access
instructions for block parameters.
getblockparam checks VM_FRAME_FLAG_MODIFIED_BLOCK_PARAM and
if it is not set this instruction creates a Proc object from
a given blcok and set VM_FRAME_FLAG_MODIFIED_BLOCK_PARAM.
setblockparam is similar to setlocal, but set
VM_FRAME_FLAG_MODIFIED_BLOCK_PARAM.
* compile.c: use get/setblockparm instead get/setlocal instructions.
Note that they are used for method local block parameters (def m(&b)),
not for block local method parameters (iter{|&b|).
* proc.c (get_local_variable_ptr): creates Proc object for
Binding#local_variable_get/set.
* safe.c (safe_setter): we need to create Proc objects for postponed
block parameters when $SAFE is changed.
* vm_args.c (args_setup_block_parameter): used only for block local blcok
parameters.
* vm_args.c (vm_caller_setup_arg_block): if called with
VM_CALL_ARGS_BLOCKARG_BLOCKPARAM flag then passed block values should be
a block handler.
* test/ruby/test_optimization.rb: add tests.
* benchmark/bm_vm1_blockparam*: added.

patch allocates a dummy NODE as auto variable, and discard it soon.

When no instruction is emitted in `iseq_compile_each0`
(i.e., when the line has no significant code), trace
instruction for `RUBY_EVENT_LINE` has been optimized out.
But trace for `RUBY_EVENT_COVERAGE` has not been removed.
Now, it is also removed.
`TestISeq#test_to_a_lines` has failed a long time under
coverage measurement (`make test-all COVERAGE=true`).
This change makes it pass.

To prepare new measuring targets: branch and method coverages.
So far, iseq->coverage was an array of counts executed for line coverage.
Now, it is a three-element array for each measuring target,
whose first element is an array for line coverage.
The second element is planned for branch coverage, and the third will be
for method coverage.
