Nikita Popov 2772751b58 Make constexpr compilation robust against multiple compilation ...

Instead of setting the old AST type to zero, replace the AST with
the compiled constexpr AST zval. This requires passing in a
zend_ast** instead of a zend_ast*.

This allows compiling ASTs containing constexprs multiple times
-- the second time, the existing compiled representation will be
resused.

This means we no longer need to copy the attributes AST for
promoted properties.
