8795893f4f Make sure string property/class const values are interned 
This was done for user-definde class constant values, however this
is also important for properties and internal classes.

33b094479b TYPE_CHECK instruction changed. Now it keeps in extended_value a type mask. 
This makes check for "boolean" cheaper and allows check combination e.g. (is_string($a) || is_null($a))

9fbb019848 Move adjust_for_fetch_type directly after emission 
And drop the distinction between compile_X and compile_X_common.
This avoids WTF moments like compile_simple_var_no_cv completely
ignoring the BP_VAR type passed to it...

d9da166649 Minor fetch type adjustment cleanup 
No need to call adjust_fetch_type on FETCH_THIS, just to special
case it in adjust_fetch_type...

fcc08ce19f Prevent reference-counting on persistent zvals (internal constants, default properties and constants of internal classes). 
New macro ZVAL_COPY_OR_DUP() is used perform duplication, if necessary.
This should eliminate related race-coditions in ZTS build and prevent reference-counting bugs after unclean shutdown.

49ea143bbd Encapsulate reference-counting primitives. 
Prohibit direct update of GC_REFCOUNT(), GC_SET_REFCOUNT(), GC_ADDREF() and GC_DELREF() shoukf be instead.
Added mactros to validate reference-counting (disabled for now).
These macros are going to be used to eliminate race-condintions during reference-counting on data shared between threads.
