to solve an issue reported at [ruby-dev:44413] [Ruby 1.9 - Bug #5217].
Before this fix, each instruction has an information including
line number (iseq::iseq_insn_info_table). Instead of this data
structure, recording only line number changing places
(iseq::iseq_line_info_table).
The order of entries in iseq_line_info_table is ascending order of
iseq_line_info_table_entry::position. You can get a line number
by an iseq and a program counter with this data structure.
This fix reduces memory consumption of iseq (bytecode).
On my measurement, a rails application consumes 21.8MB for
iseq with this fix on the 32bit CPU. Without this fix, it
consumes 24.7MB for iseq [ruby-dev:44415].
* proc.c: ditto.
* vm_insnhelper.c: ditto.
* vm_method.c: ditto.
* vm.c (rb_vm_get_sourceline): change to use rb_iseq_line_no().

[Feature #5000]

* compile.c, eval.c, iseq.c, object.c, parse.y, proc.c, process.c,
thread.c, vm.c, vm_eval.c, vm_insnhelper.c, vm_method.c: don't
declare internal functions.
Note that rb_method_entry_eq() is defined in vm_method.c but
there was a declaration in proc.c with different const-ness.
Now it is declared in method.h with same const-ness to the
definition.
* object.c (rb_mod_module_exec): don't declare functions declared in
include/ruby/intern.h.

an exception when "class Foo::Bar" is evaluated and Foo::Bar is
private. To implement this, define_type of "defineclass" is added
so that the instruction can distinguish whether the class definition
is scoped (class Foo::Bar) or not (class Bar).

test/ruby/test_module.rb
(test_define_module_under_private_constant): add tests for above.

these bugs.

definition. based on a patch from wanabe <s.wanabe AT gmail.com>
for "return". [ruby-core:21379] [ruby-dev:40975]
* insns.def (defineclass): ditto (straightforwardly push block ptr,
instead of dfp ptr with special flag).

a path to corresponding source file. or nil when the iseq is created
from -e, stdin, eval, etc. This field is used for require_relative.

(OFFSET to IC). This IC must be same as corresponding
getinlinecache instruction's IC operand.
This change is for a little performance improvement
(getting IC directly) and is for the AOT compilation development.
* compile.c, iseq.c, insns.def: Change the approach to handling inline
cahce (IC) type operand to enable the above change.
This change also affects ISeq#to_a method. The inline cache operand
will be dumped by fixnum, the index of inline cache, in other words,
inline cache identity.
* template/insns_info.inc.tmpl, tool/instruction.rb: No need to count
inline cache size (insn_iclen()).
