65e456f364 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.

4440436821 Forbid use() of auto-globals 
We don't correctly support it, it doesn't make sense and it's also
forbidden for parameters.

88eae43ff9 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.

42c8f5e91d Fix bug #70804 
This follows on from a4648ded43 and
4e01269082.
Both -(+0.0) and +(-0.0) behaved incorrectly for the same reason.

56f1106162 Use FETCH_CLASS_EXCEPTION for instanceof 
This does not collide with NO_AUTOLOAD -- missing classes will be
silenced, but invalid use of self etc will result in an exception
instead of a fatal error.

0919178963 Add result op for ASSERT_CHECK to fix SSA 
Otherwise one source of the phi node at the join point will be
borked.

I'm marking the ASSERT_CHECK result as unused in pass2, which is
a bit ugly.

8e5e3301a1 Make ZEND_CLONE return a TMP_VAR 
As the return value can't be reference and it's unlikely to be
unused.

Also remove some unnecessary checks for ce==NULL. A ce is required
nowadays.

c8a64e289c Reintroduce use of FETCH_GLOBAL_LOCK 
Just found this old AST todo...

It no longer makes sense as an optimization due to the introduction
of BIND_GLOBAL, however it ensures that the global variable name is
not evaluated twice, which is presumably something we wish to
guarantee.
