Move zend_object->guards into additional slot of zend_object->properties_table[]. As result size of objects without __get/__set/__unset/__isset magic methods is reduced.

Implement return types

RFC is documented here: https://wiki.php.net/rfc/return_types

zend_read_property() has to provide a holder for return value.
Previously it was possible that zend_read_property() returned pointer to zval allocated on stack.

Fix uninitalized variables reads. See CWE-457 for more info.

Handle run-time cache for static properties directly in executor.
Removed cache_slot argument in zend_std_get_static_property() and zend_std_unset_static_property().

trailing whitespace removal

Drop duplicate arg from hash_get_current_key_ex

Don't count variadic argument in zend_func.common.num_args. This allows faster CALL/RETURN code.

first shot remove TSRMLS_* things

Removed ZEND_ACC_FINAL_CLASS which is unnecessary. This also fixed some currently defined classes as final which were just not being considered as such before.

Reduced size of zend_op on 64-bit systems.

the main idea - the smaller the zend_op structure, the lees memory traffic is required to load VM instructions during execution. The patch reduces the size of each opcode from 48 to 32 bytes (saves 16 bytes for each opcode, and applications use thousands of opoceds). This reduced the number of CPU cache misses by 12% and improved performance of real-life apps by 1-2%.

The patch affects how constants and jump targets are represented in VM during execution. Previously they were implemented as absolute 64-bit pointers. Now they are relative 32-bit offsets.

In run-time constant now should be accessed as:
RT_CONSTANT(op_array, opine->op1) instead of opline->op1.zv
EX_CONSTANT(opline->op1) instead of opline->op1.zv

Jump targets:
OP_JMP_ADDR(opline, opline->op2) instead of opline->op2.jmp_addr

The patch doesn't change zend_op representation for 32-bit systems. They still use absolute addresses. The compile-time representation is also kept the same.

Use zend_string* for op_array->arg_info[]->name and op_array->arg_info[]->class_name. For internal functions we still use char*.

removed useless check

the offset member is an unsigned

Improved object property access.

fix datatype mismatches

sizeof(struct _string) doesn't increase.

Optimized property access handlers. Removed EG(std_property_info).

more exts converted for static tsrm ls pointer

mbstring, pcre, reflection

Fix invalid zend_string_frees in reflection

zend_lookup_class can share the name

Remove support for classes without class entries

get_class_entry must be non-NULL and return non-NULL.

Fix accidental edit in previous commit

Fix arginfo

Replaced EG(This) and EX(object) with EX(This).
Internal functions now recieves zend_execute_data as the first argument.
