Thorin segfault on unreachable code when emitting LLVM

[richardmembarth]

The following code segfaults when generating LLVM code due to unreachable code (llvm.cpp:321):

extern "C" {
  fn sqrtf(f32) -> f32;
}
extern
fn thorin_test() -> () {
    let check: [float * 1]; 
    let X = ~[12:float];
    let sval = sqrtf(X(0));
    if check(0) > 0f { }   
}

The variable check needs an initializer. If you provide one, this now works on master. I tested the program with these initializers:

• undef[[float * 1]]()
• [1.0f]
• [-1.0f]

I am therefore closing this issue.
