7 * Usage:

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