`putstring' for all of strings used by NODE_DSTR because
ruby users can not grab this string.
For example, the string object of "baz" in "foo#{bar}baz"
is located by `putobject' (users can not touch "baz" object
directly). This change reduces GC pressure.
This improvement is suggested by Aaron Patterson.

use only a `ci' (rb_call_info_t) parameter instead of using
parameters such as `op_id', 'op_argc', `blockiseq' and flag.
These information are stored in rb_call_info_t at the compile
time.
This technique simplifies parameter passings at related
function calls (~10% speedups for simple mehtod invocation at
my machine).
`rb_call_info_t' also has new function pointer variable `call'.
This `call' variable enables to customize method (block)
invocation process for each place. However, it always call
`vm_call_general()' at this changes.
`rb_call_info_t' also has temporary variables for method
(block) invocation.

rb_location_t#filename, filepath, name and line_no was moved from
rb_iseq_t. rb_location_t#basename is a new field which is
similar to `name' field without any decoration.
`name' field contains some decoration such as `block in foo'.
`basename' only contains `foo'.
rb_iseq_t contains memory object of rb_location_t.
* iseq.c: setup rb_location_t for each rb_iseq_t memory objects.

Divide big array (or hash) literals into several blocks and
concatetene them. There was a problem that a big array (hash)
literal causes SystemStackError exception (stack overflow)
because VM push all contents of the literal onto VM stack to
make an array (or hash). To solve this issue, we make several
arrays (hashes) and concatenate them to make a big array (hash)
object.

* id.c (Init_id), parse.y: add core method ids.

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].
