Use zend_string_release_ex() instread of zend_string_release() in places, where we sure about string persistence.

Don't use optimize pragmas with clang

Fixed bug #76025 (Segfault while throwing exception in error_handler).

Allow generation of VM map

Fixed compilation warnings

Fixed build without global register variables

Reorganize make_real_object() related code

Move exceprional code into helper & zend_fetch_var_address_helper() micro-optimization.

Move result address calculation from specialized handlers to less specialized helpers

Mark exceptional helpers as "cold"

Move exceptional code into helpers

Move cold code, duplicated by specializer, into helper functions

Fixed build without global register variables

Separate slow path with make_real_object() and related code into "cold" function.

Separate cold paths of ISSET_ISEMPTY_DIM_OBJ

Added tracer to collect frequency of opcode handler call chains

Avoid live range references in opcodes

Don't store the live range of the freed variable for FREE_ON_RETURN
frees, instead look it up at runtime. As this is an extremely
unlikely code

Avoid live range references in opcodes

Don't store the live range of the freed variable for FREE_ON_RETURN
frees, instead look it up at runtime. As this is an extremely
unlikely codepath (in particular, it requires a loop variable with
a throwing destructor), saving the runtime lookup of the live range
is not worth the extra complexity this adds everywhere else.

Move exceptional code into "cold" helpers

Use Z_TYPE_INFO_REFCOUNTED() macro

Moved "zval.u2.cache_slot" into free room of "zend_op"

Avoid repeatable ARG_SHOULD_BE_SENT_BY_REF() checks in FETCH_*FUNC_ARG and following SEND_VAR_EX. Perform the check once in a new CHECK_FUNC_ARG opcode and reuse in the following FETCH_*FUNC_ARG and

Avoid repeatable ARG_SHOULD_BE_SENT_BY_REF() checks in FETCH_*FUNC_ARG and following SEND_VAR_EX. Perform the check once in a new CHECK_FUNC_ARG opcode and reuse in the following FETCH_*FUNC_ARG and SEND_FUNC_ARG (SEND_VAR_EX replacement).

Break dependency between IS_TYPE_REFCOUNTED and ZEND_CALL_FREE_EXTRA_ARGS

Avoid redundand mask extraction

Change FETCH/ISSET instruction modifiers:
- Get rid of ZEND_ISEMPTY and ZEND_ISSET_ISEMPTY_MASK. Use just single ZEND_ISSET bit to make distinct between isset() and empty()
- Use ZEND_FETCH_G

- Use ZEND_FETCH_GLOBAL, ZEND_FETCH_LOCAL and ZEND_FETCH_GLOBAL_LOCK as bitmask
- Removed unused ZEND_FETCH_STANDARD
- Extended ZEND_FETCH_ARG_MASK
