Made FETCH_DIM/OBJ_FUNC_ARG to dispatch ro corresponding FETCH_DIM/OBJ_R/_W handlers.
Merged TMP and VAR specializations of ZEND_FETCH_OBJ_R.
Allowed dispatching to less specialized handelrs and helpers. (e.g. from OP_TMP_CONST to OP_TMPVAR_CONST).
Otherwise we're missing the "expected to be a reference, value
given" warning that appears for ordinary calls to call_user_func().
Also update an UPGRADING note with recent changes wrt
call_user_func().
This slightly improves calls to regular function and method calls in cost of a bit slower generator initialization.
Separate call frame for generators, allocated on heap, now created by ZEND_GENERATOR_CREATE instruction.

list() with keys (no foreach or tests)
This opcodes inserts a local CV into the closure static variable
table. This replaces the previous mechanism of having static
variables marked as LEXICAL, which perform a symtable lookup
during copying.
This means a) functions which contain closures no longer have to
rebuild their symtable (better performance) and b) we can now track
used variables in SSA.
The DECLARE_(ANON_)INHERITED_CLASS(_DELAYED) opcodes were
referencing the parent ce VAR through extended_value. This is
hacky and we can't track the def-use chain in SSA.
To avoid this, the layout of declaration opcodes is changed
as follows: op1 points to the lcname and rtd_key literals, in
that order. (For anon/lambda declarations only one of lcname or
rtd_key is present.) This frees up op2, which is now used to
reference the parent ce VAR in inheriting declarations. The
jmp offset for anon class declarations is moved frop op2 to
extended_value.
The changes were applied both to class and function declarations
to keep everything symmetric.
- Added ZEND_VM_LAST_OPCODE macro
- Use better names LINE->OPLINE, REL_LINE->REL_OPLINE, FCALL->FAST_CALL, FRET->FAST_RET
- Added ISSET flag to extended value of ZEND_ISSET_ISEMPTY_VAR opcode
This is generalized solution for Bob's idea of speed up self::method() calls without ZEND_FETCH_CLASS.
At first, it adds few new opcodes to separate class related behaviour:
FETCH_STATIC_PROP_R
FETCH_STATIC_PROP_W
FETCH_STATIC_PROP_RW
FETCH_STATIC_PROP_FUNC_ARG
FETCH_STATIC_PROP_UNSET
FETCH_STATIC_PROP_IS
UNSET_STATIC_PROP
ISSET_ISEMPTY_STATIC_PROP
FETCH_CLASS_CONSTANT
At seconds, it enables IS_UNUSED operand to fetch (self, parent or static without separate FETCH_CLASS) for new opcodes and the following ones:
INIT_STATIC_METHOD_CALL
NEW
END_INSTANCEOF
Finaly, opcache optimizer had to be fixed to support new opcodes.
