cfp->bp was (re-)introduced by Kokubun san, but VM doesn't use it
because I (ko1) want to remove it in a future. But using it make
leave instruction fast because of sp consisntency check.
So now VM uses cfp->bp.
To use cfp->bp, I checked the value and I found that it is not a
"initial value of sp" but a "initial value of ep". Fix this problem
and fix all bp references (this is why bp is renamed to bp_).

Add counters to count ccf (call cache fastpath) usage.
These counters will help which kind of method dispatch
is important to optimize.

similar idea to r67315, provide the following optimization
for method dispatch with lead and kw parameters.
(1) add a special branch to check passing kw arguments to
a method which has lead and kw parameters.
ex) def foo(x, k:1); end; foo(0, k:1)
(2) add a special branch to check passing no-kw arguments to
a method which has lead and kw parameters.
ex) def foo(x, k:1); end; foo(0)
For (1) and (2) cases, provide special dispatchers. For (2) case,
this patch only use the special dispatcher if all default
kw parameters are literal values (nil, 1, and so on. In other case,
kw->default_values does not contains Qundef) (and no required kw
parameters becaseu they don't pass any keyword parameters).
Passing keyword arguments with a hash object is not a scope of
this patch.
Without this patch, (1) and (2) cases use `setup_parameters_complex()`.
Especially, (2) seems frequent case for methods which extend a normal
usecase with keyword parameters (like: `exception: true`).
We can measure the performance with benchmark-driver:
With methods: def kw k1:1, k2:2; end
def m; end
With the following binaries:
clean-miniruby: unmodified trunk.
opt_miniruby1: use special branches for lead/kw parameters.
opt_miniruby2: use special dispatchers for lead/kw parameters.
opt_cc_miniruby: apply step (2).
Result with benchmark-driver:

without MJIT_STATIC is harmful for mswin JIT system.

* explanation of the class concept, with examples;
* docs for all class methods (most of them just say "Like Enumerable#<methodname>, but chains operation to be lazy-evaluated.", but I believe they are useful this way because now have proper call-sequences and link to corresponding Enumerable's explanations)
* simplified example for ::new to emphasize the main concept
* Enumerable#lazy docs are slightly lightened and linked to this class for more in-depth explanations.

There is a special optimization for "only lead parameters"
method dispatch using specialized dispatcher functions
`vm_call_iseq_setup_normal_0start...`.
Other cases (opt, rest, post, ...) we don't use specialized
dispatcher and call with `setup_parameters_complex` to
satisfy Ruby's complex parameter specification.
This commit introduce a specialize dispatcher for
methods which use only lead and optional parameters.
Two step improvements:
(1) prepare "lead/opt" only check pass.
It is to skip the `setup_parameters_complex` function.
(2) introduce specialized dispatcher for only "lead/opt"
parameters methods (vm_call_iseq_setup_normal_opt_start).
With these improvements, we achieved good micro-benchmark
results:
With a method: `def opt2 a, b=nil; end`
With the following binaries:
clean-miniruby: unmodified trunk.
opt_miniruby: apply step (1).
opt_cc_miniruby: apply step (2).
Result with benchmark-driver:
opt2(1)
opt_cc_miniruby: 42269409.1 i/s
opt_miniruby: 36304428.3 i/s - 1.16x slower
clean-miniruby: 25897409.5 i/s - 1.63x slower
opt2(1, 2)
opt_cc_miniruby: 45935145.7 i/s
opt_miniruby: 40513196.9 i/s - 1.13x slower
clean-miniruby: 29976057.6 i/s - 1.53x slower
This improvement may be trivial (difficult to improve practical
cases). However, this is enough small patch so I decide to
introduce it.
