Description:
------------
Under thread-safe builds the registered_zend_ini_directives hash table leaks (verified under Win32 with a _CrtDumpMemoryLeaks() call at the bottom of the CLI main() function).  There is a zend_ini_global_shutdown() function in zend_ini.c to free this table, but it never gets called.

A suggested patch:

 #ifndef ZTS
-	zend_ini_shutdown(TSRMLS_C);
 	shutdown_memory_manager(CG(unclean_shutdown), 1 TSRMLS_CC);
 #endif
 
Since registered_zend_ini_directives is the same as EG(ini_directives) under non-thread safe builds, calling zend_ini_global_shutdown() in either case should be fine.

Reproduce code:
---------------
Just calling "php.exe -v" caused the memory leak - no script is required.
