This method type is for optimized CFUNC such as Fixnum#+ and so on.
This feature is half-baked and no way to use them.
[Background]
Now, VM has opt_plus instructions to optimize `+' methods for
some Classes (such as Fixnum, Float (flonum)). We call this
type of instructions as `specialized instructions'.
This simple technique improve simple program dramatically.
However, we can make specialized instructions for only several
types (classes) and selectors (method names) because a large
instruction will be slow. In other words, this technique has no
extensibility.
To overcome this problem, VM_METHOD_TYPE_CFUNC_FRAMELESS was
introduced (r37198). This type is a variant of CFUNC, but called
their functiions directly without building a method frame.
Any CFUNC method can be defined as frameless methods if a method
is not needed to make method frame. Frameless methods are faster
as specialized instructions (a bit slower, but no need to care).
No problem described at
http://charlie.bz/blog/why-do-singleton-methods-make-ruby-slow
because this technique doesn't see class, but see method body
itself. Alias is also no problem.
[Problem]
However, we can't set frameless method type for polymorphic methods
such as Array#[]. Necessity for method frame depends on which
parameter type. For example, Fixnum#+ needs method frame if
coerce is needed. Current VM_METHOD_TYPE_CFUNC_FRAMELESS is not
flexible and need more tuning to introduce it.
Expected behavior of frameless method type may be:
result = optimized_cfunc(params); /* call optimized cfunc */
if (result == Qundef) { result = normal_cfunc(); }
This is why I say this feature is half-baked.
We need to learn primitive method in Smalltalk more.
(I heard this name at RubyConf Taiwan this month. Thanks!)
[Conclusion]
Nobody may use this feature and there is no compatibility issue.
This feature goes to next minor (2.1?).

This method is similar to VM_METHOD_TYPE_CFUNC methods, but
called cfunc without building new frame (does not push new control
frame). If error is occured in cfunc, the backtrace only shows

dfp (dynamic frame pointer) to ep (environment pointer).
This change make VM `normal' (similar to other interpreters).
Before this commit:
Each frame has two env pointers lfp and dfp. lfp points
local environment which is method/class/toplevel frame.
lfp[0] is block pointer.
dfp is block local frame. dfp[0] points previous (parent)
environment pointer.
lfp == dfp when frame is method/class/toplevel.
You can get lfp from dfp by traversing previous environment
pointers.
After this commit:
Each frame has only `ep' to point respective enviornoment.
If there is parent environment, then ep[0] points parent
envioenment (as dfp). If there are no more environment,
then ep[0] points block pointer (as lfp). We call such ep
as `LEP' (local EP). We add some macros to get LEP and to
detect LEP or not.
In short, we replace dfp and lfp with ep and LEP.
rb_block_t and rb_binding_t member `lfp' and `dfp' are removed
and member `ep' is added.
rename rb_thread_t's member `local_lfp' and `local_svar' to
`root_lep' and `root_svar'.
(VM_EP_PREV_EP(ep)): get previous environment pointer. This macro
assume that ep is not LEP.
(VM_EP_BLOCK_PTR(ep)): get block pointer. This macro assume
that ep is LEP.

(VM_ENVVAL_BLOCK_PTR(ptr)): make block pointer.

Because following two reason:
* Proc#arity's return value with optional arguments is not clear.
The optional argument for proc/lambda is Ruby 1.9 feature.
In 1.9, proc(a, b=1){} can receive 1 or more arguments.
But lambda(a, b=1){} can receive only 1 or two arguments.
r33921 breaks lambda's arity.
The spec arround optional arguments of proc/lambda needs more

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].
