fafe01b07b Make call_user_func() on reference args consistent 
Previously reference arguments were allowed if call_user_func()
was compiled to SEND_USER and not otherwise. Make it consistent
by always forbidding them.

Alternatively could throw some kind of uncatchable dummy exception
into the generator. Right now just checking for NULL in two places
seems simpler.

4746e5efcb Forbid "yield from" in force closed generators 
Same check we do for "yield", was missed when "yield from" was
added. We could make this more granular by only forbidding to
actually yield values and still allow something like "yield from []",
but this does not seem worthwhile.

8f7b1a3248 IS_CONST operands don't have to be separated. Use reference-counting instead of duplication. 
- with opcache all IS_CONST operands are not refcounted (scalars, interned strings or immutable arrays)
- without opcache IS_CONST operands are not shared between processes or threads and may use common reference counters

ccf18da450 Eliminated checks for (func->op_array.fn_flags & ZEND_ACC_GENERATOR) in fast path of DO_FCALL* handlers. 
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.
