Implicit return should be always on the last line of a function

Also add all class statements to unticked statements, these would
generate superfluous EXT_STMT/TICKS in the parent op_array.

Fix bug #70106 (Inheritance by anonymous class)

Ignore getcwd return in zend_compile

To do this move the php_ignore_value macro to ZEND_IGNORE_VALUE.

Fixed bug #70240 (Segfault when doing unset($var());)

Fixed no return statement in function returning non-void

Fix __METHOD__ in functions nested into methods

Better implementation

hmm, we do not need the nop after compilation, so does not matter for opcache...

a: try { ... } ≠ try { a: ... }

Resolve GOTO at compile time and replace it with sequnce of FREE/FE_FREE and JMP.

Exception thrown by "return" statement (from TMP destructors) shouldn't be caught in the same function

Revert "Fixed bug #62210 (Exceptions can leak temporary variables. 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)"

Fixed situation, when CHECH_EXCEPTION() might change value of "opline" variable and the following "opline" useages would access elements of different opcode. That might lead to unpredictable behavior. (Only PHP-7 with GCC global register variables was affected).
CHECK_EXCEPTION() macro is removed. ZEND_VM_NEXT_OPCODE_CHECK_EXCEPTIO() should be used instead. It's equivalent to old CHECK_EXCEPTION() + ZEND_VM_NEXT_OPCODE().
As a side effect, this also slightly improved performnce of builds with GCC >= 4.8.
