This changes Thread::Location::Backtrace#absolute_path to return
nil for methods/procs defined in eval. If the realpath of an iseq
is nil, that indicates it was defined in eval, in which case you
cannot use RubyVM::AbstractSyntaxTree.of.

Now ISeq#to_a includes the node_id list for each bytecode instruction.
I want a way to retrieve the AST::Node instance corresponding to an
instruction for a research purpose including TypeProf-based LSP server.
RubyVM::AST.of(Thread::Backtrace::Location) returns a node that
corresponds to the location. Typically, the node is a method call, but
not always.
This change also includes iseq's dump/load support of node_ids for each
instructions.
by merging `rb_ast_body_t#line_count` and `#script_lines`.
Fortunately `line_count == RARRAY_LEN(script_lines)` was always
satisfied. When script_lines is saved, it has an array of lines, and
when not saved, it has a Fixnum that represents the old line_count.
This option makes the parser keep the original source as an array of
the original code lines. This feature exploits the mechanism of
`SCRIPT_LINES__` but records only the specified code that is passed to
RubyVM::AST.of or .parse, instead of recording all parsed program texts.
... then, new_insn_core extracts nd_line(node).
Also, if a macro "EXPERIMENTAL_ISEQ_NODE_ID" is defined, this changeset
keeps nd_node_id(node) for each instruction. This is intended for
TypeProf to identify what AST::Node corresponds to each instruction.
This patch is originally authored by @yui-knk for showing which column a
NoMethodError occurred.

Was this an autogenerated function? This tendency of avoiding empty
branches are no longer preserved (see for instance NODE_IVAR). Let's
just delete those unnecessary jumps into branches.
Saves comitters' daily life by avoid #include-ing everything from
internal.h to make each file do so instead. This would significantly
speed up incremental builds.
We take the following inclusion order in this changeset:
1. "ruby/config.h", where _GNU_SOURCE is defined (must be the very
first thing among everything).
2. RUBY_EXTCONF_H if any.
3. Standard C headers, sorted alphabetically.
4. Other system headers, maybe guarded by #ifdef
5. Everything else, sorted alphabetically.
Exceptions are those win32-related headers, which tend not be self-
containing (headers have inclusion order dependencies).
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.
* Make it clear as possible that RubyVM is MRI-specific and only exists on MRI
* See [Bug #15743].
* Use "CRuby VM" instead of "Ruby VM" for clarity.
* Use YARV rather than "CRuby VM" for documenting RubyVM::InstructionSequence
* Avoid introducing a new "CRuby VM" term in documentation
* ast.c (rb_ast_node_type): simplified to return a Symbol without
"NODE_" prefix.
