This reduces the iseq_compile_data_storage header from 32 to 16
bytes on 64-bit systems.
pos and size fields cannot exceed 32-bit sizes due to stack size
limits. Using a flexible array for the buffer also saves us 8
bytes of pointer overhead.

* iseq.h (iseq_catch_table_bytes): check range and suppress a
warning.

* iseq.h (struct iseq_catch_table_entry): shrink to 32 bytes on 64-bit
This drops a few minor page faults on my system at startup.
Using 64-bit start, end, cont, and sp fields are unnecessary as
label_get_position and label_get_sp only return int values.
label_get_position and label_get_sp should probably return
unsigned, but that is a future change.

Most iseq do not have a catch_table, so avoid needlessly adding
4-8 bytes to the struct for the common case.
Changes from v2:
- iseq_catch_table_size removed, use if (...) for (;...;)
Changes from v1:
- renamed iseq->_catch_table to iseq->catch_table
- iseq_catch_table_bytes: made a static inline function
- iseq_catch_table_size: new function replaces the
iseq_catch_table_each iterator macro
* iseq.h (struct iseq_catch_table): new flexible array struct
(iseq_catch_table_bytes): allocated size function
* vm_core.h (struct rb_iseq_struct): uupdate catch_table member

rb_data_type_struct::flags. Now, this flags is passed
at T_DATA object creation. You can specify FL_WB_PROTECTED
on this flag.
* iseq.c: making non-shady iseq objects.
* class.c, compile.c, proc.c, vm.c: add WB for iseq objects.
* vm_core.h, iseq.h: constify fields to detect WB insertion.

* vm_core.h (rb_iseq_t): move flip_cnt from struct iseq_compile_data,
because it has same life span as enclosing iseq. [Bug #7671]

* compile.c (iseq_compile_each): count flip-flop state in local iseq
not in each iseqs, so that the keys can be other than hidden
strings. [ruby-core:47253] [Bug #6899]
* vm_insnhelper.c (lep_svar_get, lep_svar_set, vm_getspecial): store
flip-flop states in an array instead of a hash.
* iseq.c (set_relation): main iseq also can has local scope.

Fixnum because they are pushed into Array in a compiler.
[Bug #7502]
* test/ruby/test_objectspace.rb: add a test of this issue.

* iseq.c: add following two methods.
* ISeq#line_trace_all returns all line traces (line numbers)
* ISeq#line_trace_specify(pos, set) set `pos'th line event to
specified_line event (if set is true).
These features are introduced for debuggers (mainly to make
breakpoint).
* iseq.h: add decl. of C APIs.
* test/ruby/test_iseq.rb: add tests.
* vm_trace.c: add `specified_line' event.
* include/ruby/ruby.h: ditto.

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().

* 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.
