This reverts commit bac6fdb0c52c924e726c5a78de8858bf27b6586b.

Refactor zval cleanup into single function

Also use zval_ptr_dtor_nogc() everywhere in Zend in favor of zval_dtor()

Introduce BIND_LEXICAL

This opcodes inserts a local CV into the closure static variable
table. This replaces the previous mechanism of having static
variables marked as LEXICAL, which perform a symtable lookup
during copying.

This means a) functions which contain closures no longer have to
rebuild their symtable (better performance) and b) we can now track
used variables in SSA.

Add myself into list of authors of the most refactored files.

Improved reference counting

Use fastcall calling convention for most critical ZE subsystems.

bump year

trailing whitespace removal

first shot remove TSRMLS_* things

Moved i_zval_ptr_dtor() from zend_execute.h to zend_variables.h

fix datatype mismatch warnings

Fixed compilation warnings

Use zval_ptr_dtor_nogc to destroy literals

Also move the definition of zval_ptr_dtor_nogc to zend_variables.h
(from zend_execute.h/.c) as it's used in a few places.

Optimized conditions order

Introduced immutable arrays. They don't need to be copyed and may be used directly from SHM.

Use zval_get_string in print_zval and propagate TSRMLS

Cleanup (1-st round)

Various VM optimizations

Refactored ZVAL flags usage to simplify various checks (e.g. Z_REFCOUNTED(), candidate for GC, etc)

Refactored GC (incomplete)
