As per https://wiki.php.net/rfc/remove_alternative_php_tags.
Removes:
* <% opening tag
* %> closing tag
* <%= short opening tag
* /<script\s+language\s*=\s*(php|"php"|'php')\s*>/i opening tag
* /</script>/i closing tag
* asp_tags ini directive
* coalesce_operator:
Extended coalesce operator test case for ordering/short-circuiting
Ensure not evaluated twice
Added test
Initial coalesce operator implementation
* generators: (70 commits)
Fix typos
Fix segfault when traversing a by-ref generator twice
Make sure that exception is thrown on rewind() after closing too
Remove implementation stubs for yield delegation
Fix several issues and allow rewind only at/before first yield
Run finally if generator is closed before finishing
Finally with return now works in generators too
Add dedicated opcode for returns from a generator
Disallow serialization and unserialization
Fix zts build (typo)
Drop Generator::close() method
Forgot to add test
Support trivial finally in generators (no yield, no return)
Fix implementation of Iterator interface
Add T_YIELD in tokenizer_data.c
Throw error also for return occuring before yield
Fix throwing of exceptions within a generator
Remove reference restrictions from foreach
Require parenthesis around yield expressions
Add some more tests
...
This is just an intial merge. It does not yet make generators and finally
work together.

foreach only allowed variables to be traversed by reference. This never
really made sense because
a) Expressions like array(&$a, &$b) can be meaningfully iterated by-ref
b) Function calls can return by-ref (so they can also be meaningfully
iterated)
c) Iterators could at least in theory also be iterated by-ref (not
sure if any iterator makes use of this)
With by-ref generators the restriction makes even less sense, so I removed
it altogether.
