* Generator for SIMPLE_IPA pass related boilerplate code/data

* Usage:
*
* 1. before inclusion define PASS_NAME
* 2. before inclusion define NO_* for unimplemented callbacks
* NO_GATE
* NO_EXECUTE
* 3. before inclusion define PROPERTIES_* and TODO_FLAGS_* to override
* the default 0 values
* 4. for convenience, all the above will be undefined after inclusion!
* 5. the only exported name is make_PASS_NAME_pass() to register with gcc
