coccinelle: drop a couple of FIXMEs
Turns out Coccinelle can handle compound literals just fine, the parsing errors were caused by incorrectly parsed macros in code before the literals, so let's just provide simplified versions for such macros. The parsing error in `Type *foo[ELEMENTSOF(bar)] = {};` is actually harmless; it occurs only when creating an array of pointers for a type that's in an external header and it occurs only on the first parser's pass, subsequent passes resolve the type correctly. Also, unset ENABLE_DEBUG_HASHMAP, so Coccinelle doesn't expand the hashmap debug macros. As for the remaining FIXMEs, I opened a couple of issues in the Coccinelle upstream to see if they can be fixed there (or at least properly analyzed).
