Bug description:GDB：____executor_globals fails when EG/CG symbol may not visible in some module

Description:
------------
when debug using GDB, sometime ____executor_globals failed to execute 
because in some module eg:zend_gc.c did have zend_executor_global
exposed(Only ZTS 
model affected，since executor_globals always available).

Test script:
---------------
(gdb) b gc_zval_possible_root
Breakpoint 1 at 0x1005aa7d0: file zend_gc.c, line 132.
(gdb) r circle.php 
Starting program: /Users/reeze/Opensource/php-src/sapi/cli/php circle.php
Reading symbols for shared libraries ++++++.......................... done

Breakpoint 1, gc_zval_possible_root (zv=0x100dcbb58, tsrm_ls=0x100e009b0)
at zend_gc.c:132
warning: Source file is more recent than executable.
132		if (UNEXPECTED(GC_G(free_list) != NULL &&
(gdb) printzv zv
No symbol "zend_executor_globals" in current context.

Expected result:
----------------
print zval correctly

Actual result:
--------------
No symbol "zend_executor_globals" in current context.
