Introduce BIND_LEXICAL
...
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.

Remove uses of VARs in extended_value
...
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.

Speed up fetching of class entries for self:: parent:: and static::
...
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.
