Allow an experimental VM with tail call dispatch technique (disabled by default).
...
This VM may work only if all tail calls are optimized, otherwaise it will crach because of stack overflow.
Unfortunately, we can't guarantee tail call optimization in 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.
