This ports 247105ae1ae2a04608078f7fcfe88dacab9f55a4 to the JIT
implementation. The issue doesn't trigger on the original test
case with JIT, but I ran into a case that does trigger with JIT
once we have typed properties.

Mark various functions with void arguments.

This fixes a bunch of [-Wstrict-prototypes] warning,

Fast Class Cache

This is generalization of idea, that was previously usesd for caching
resolution of class_entries in zend_type. Now very similar mechanizm is
used for general zend_string into zend_class_entry resolution.

Interned zend_string with IS_STR_CLASS_NAME_MAP_PTR GC_FLAG uses its
refcount to adress corresponding zend_class_entry cache slot.
The refcount keeps an offset to this slot from CG(map_ptr_base).
Flag may be checked by ZSTR_HAS_CE_CACHE(str), cache slot may be read by
ZSTR_GET_CE_CACHE(str) and set by ZSTR_SET_CE_CACHE(str, ce).
