Dont't use DO_ICALL for internal functions returned by reference

Slight improvement

Fixed compiler warning

Use fast method to check if first arguments should be passed by reference (not tested onbig endian).

Move more stuff to file_context

Introduce helper macro FC(x) for CG(file_context).x.

end_compilation() now handled by file_context_end().

While at it, dropped zval wrapper

Fixed bug #69388

Renamed compiler_context to oparray_context. Introduced per-file
file_context. Moved import tables into the file_context.

context_stack no longer exists, instead keeping backups of contexts
on C stack. Same for file contexts.

TODO: Move more things out of CG into file_context. There should be
a number of other things that we should not try to reuse in nested
compilations.

Finish PHP 4 constructor deprecation

Implement additional type reservations

* The class names false, true and null are now reserved.
* The code dealing with reserved class names is now decoupled
from scalar type hint handling. It also includes self, parent,
and static, which are class names which were already reserved
previously.
* Reuse existing messages for reserved class names.

Fallout: class_alias() can no longer alias self, parent and static.
However this never really worked in the first place, as the test
which was testing this shows.

Disallow direct incdec of function return value

Matching PHP 5 behavior.

We may want to support this for by-reference returns, but that
requires implementing further checks.

Change "Cannot redeclare class X" into "Cannot redeclare class/interface/trait X", meaning that the following:

C:\> php -r "trait A { } trait A { }"

Will now properly print "Cannot

Change "Cannot redeclare class X" into "Cannot redeclare class/interface/trait X", meaning that the following:

C:\> php -r "trait A { } trait A { }"

Will now properly print "Cannot redeclare trait A" instead of "Cannot redeclare class A" to make error messages a tiny bit clearer. Admittedly, a better solution can most likely be made by actually telling what the colliding object is a type of.

Internally this adds a new function:
zend_get_object_type()

ZEND_ADD_STRING/VAR/CHAR are replaced with ZEND_ROPE_INTI, ZEND_ROPE_ADD, ZEND_ROPE_END.
Instead of reallocation and copying string on each ZEND_ADD_STRING/VAR/CAHR, collect all the strings and then allocate and construct the resulting string once.
