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 void return type

Cleanup: removed comments (zend_object.handle and zend_resource.handle are not going to be removed in PHP-7.0)

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

Simplify the macro (HT_DATA_SIZE/HT_HASH_SIZE is not used outside Zend)

Get rid of implicit type casting in GC_*() macros in Zend/zend_types.h.
This prevented compilation warnings and disclosed few incorrect usages in Zend/zend_vm_def.h and ext/dom/xpath.c.

Get rid of implicit type casting in GC_*() macros in Zend/zend_types.h.
This prevented compilation warnings and disclosed few incorrect usages in Zend/zend_vm_def.h and ext/dom/xpath.c.
Now explicit type casting may be required on call site.
This may break some C extension code, but it shoulfn't be a problem to add explicit casting.

Fixed bug #70258 and #70253

Fixed Bug #70173 (ZVAL_COPY_VALUE_EX broken for 32bit Solaris Sparc)

Fix #70173: ZVAL_COPY_VALUE_EX broken for 32bit Solaris Sparc

On 32bit big endian architectures the high word of a zend_value is copied
twice, instead of copying both words. Let's fix it.

add one more thread storage specifier to allow external link

improve ZEND_TLS declaration even more and move it to the better place

Use the new 'ZSTR' macros in the rest of the code.

Does not change anything to the generated code (thanks to compat macros) but cleaner.

Fixes for x32 ABI

I'm assuming that we want to have 64bit zend_longs on x32 here.

This fixes two typos in __x86_64__ macros and adds sign-extension
when assigning STREAM_COPY_AL

Change the GC approach to inner-loops handling. Switch to less efficient but more robust algorithm. Destructors handling is still not completely accurate.

Added GC checks and improvements

GC improved to support inner-cycles.
