The C front-end is not emitting LLVM type names for typedefs of structures. 
This is usually fine (because structs usually also have a tag), but causes us to
not emit names at all for certain structs, defined like this:

----------------------------------
typedef struct {
        double W, X, Y, Z;
} FOOTY;

void test(FOOTY* A) {}
----------------------------------

Missing the symbolic type name makes the LLVM code unreadable for some programs
like 188.ammp (and others) which have large structures defined like this.

We currently compile this testcase into:

void %test({ double, double, double, double }* %A) {
entry:
        ret void
}

Where we would like to see:

void %test(%FOOTY* %A) {
entry:
        ret void
}
