Fixed bug #70630 (Closure::call/bind() crash with ReflectionFunction->getClosure())
This additionally removes support for binding to an unknown (not in parent hierarchy) scope.
Removing support for cross-scope is necessary for certain compile-time assumptions (like class constants) to prevent unexpected results

Reordered field to improve data lacality and reduce L1D CPU cache misses in ZEND_INIT_FCALL opcode family

Simply use 0/1 instead as dmitry suggested

Make ZEND_ECHO and removed ZEND_PRINT distinguishable

Added zend_internal_function.reserved[] fields, to allow extensions keep additional associated information.
We didn't have zend_internal_function.reserved[] in PHP5, but we always allocated space

Added zend_internal_function.reserved[] fields, to allow extensions keep additional associated information.
We didn't have zend_internal_function.reserved[] in PHP5, but we always allocated space for zend_function union, and extensions were able to reuse zend_function.op_array.reserved[] even for internal function. Now this is not possible. And extensions have to use zend_function.op_array.reserved[] for user functions and zend_function.internal_function.reserved[] for internal.

This reverts commit b6936adb58288a0606ed847802d9226cddb41e2b.

This change turns out to not have been a clever idea and was causing more weirdness than it helped...

Some extensions may want to analyze or re-run the op array later

Remove FAST_CALL_FROM_CATCH

This was generated for a return from a try block with both a catch

Remove FAST_CALL_FROM_CATCH

This was generated for a return from a try block with both a catch
and a finally. However at this point no exception can be active,
because it either didn't exist in the first place or was explicitly
discarded using DISCARD_EXCEPTION.

As a part of the fix serious refactoring was done. op_array->brk_cont_array was removed, and replaced with more general and speed efficient op_array->T_liveliness. ZEND_GOTO opcode is always replaced by ZEND_JMP at compile time). (Bob, Dmitry, Laruence)"
