Also as phpdbg is included and needs such a map, it'd be counterproductive to need to change two things on every new opcode.

Implement variadic function syntax

As per RFC: https://wiki.php.net/rfc/variadics

Happy New Year

Happy New Year

An exception thrown in try or catch block is disacarded by return statement in finally block.

Restored proper generators behaviour in conjunction with "finally". (Nikita)

. The VM stacks for passing function arguments and syntaticaly nested calls were merged into a single stack. The stack size needed for op_array execution is calculated at compile time and preallocate

. The VM stacks for passing function arguments and syntaticaly nested calls were merged into a single stack. The stack size needed for op_array execution is calculated at compile time and preallocated at once. As result all the stack push operatins don't require checks for stack overflow any more.
. Generators implementation was improved using the new VM stack. Now it's a bit more clear and faster.

Improved "finally" im[plementation

Remove implementation stubs for yield delegation

I decided to leave out yield delegation for an initial proposal, so remove
the stubs for it too.

Add dedicated opcode for returns from a generator

Generators don't have a return value, so it doesn't make sense to have
a shared implementation here.

Merge remote-tracking branch 'php-src/master' into addGeneratorsSupport

This is just an intial merge. It does not yet make generators and finally
work together.

Remove asterix modifier (*) for generators

Generators are now automatically detected by the presence of a `yield`
expression in their body.

This removes the ZEND_SUSPEND_AND_RET

Remove asterix modifier (*) for generators

Generators are now automatically detected by the presence of a `yield`
expression in their body.

This removes the ZEND_SUSPEND_AND_RETURN_GENERATOR opcode. Instead
additional checks for ZEND_ACC_GENERATOR are added to the fcall_common
helper and zend_call_function.

This also adds a new function zend_generator_create_zval, which handles
the actual creation of the generator zval from an op array.

I feel like I should deglobalize the zend_create_execute_data_from_op_array
code a bit. It currently changes EG(current_execute_data) and
EG(opline_ptr) which is somewhat confusing (given the name).

Add sceleton for yield* expression

This does not yet actually implement any delegation.

Add YIELD opcode implementation

Add ZEND_SUSPEND_AND_RETURN_GENERATOR opcode

If the function is a generator this opcode will be invoked right after
receiving the function arguments.

The current implementation

Add ZEND_SUSPEND_AND_RETURN_GENERATOR opcode

If the function is a generator this opcode will be invoked right after
receiving the function arguments.

The current implementation is just a dummy.
