Ignore ill-formed C programs

trailofbits/instafix-llvm#44 is an attempted workaround
for some ill-formed C programs that we still need to support building, but it
will cause way more LLVM indirect calls to be generated, and calls to be
generated with the wrong number of arguments against the original declaration

Essentially, the issue is that some programs do

```c
int foo() { ... }
```

Then somewhere else:

```c
extern int foo(int bar);

foo(0);
```
