* Generator for IPA pass related boilerplate code/data

* Supports gcc 4.5-6

* Usage:
*
* 1. before inclusion define PASS_NAME
* 2. before inclusion define NO_* for unimplemented callbacks
* NO_GENERATE_SUMMARY
* NO_READ_SUMMARY
* NO_WRITE_SUMMARY
* NO_READ_OPTIMIZATION_SUMMARY
* NO_WRITE_OPTIMIZATION_SUMMARY
* NO_STMT_FIXUP
* NO_FUNCTION_TRANSFORM
* NO_VARIABLE_TRANSFORM
* 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
