Nikita Popov 7620ea1580 Don't intern compiled_filename ...

For php-ast interning the file name is an effective memory leak,
see php-ast#134.

I don't think there's any reason to do this. At some point this
was needed due to bugs in the interned string mechanism that
caused issues if the string was later interned, e.g. through a
__FILE__ reference. These issues have since been resolved.

In conjunction with the filenames_table removal in c4016ecd44
this means that filenames now need to be refcounted like normal
strings. In particular the filename reference in op_arrays and CEs
are refcounted.
