ir.cpp err

test.zig

The initial program I tried to run:

```
pub fn main() -> %void {
   var m2 = &2;
   %%io.stdout.printf("hello: {}\n", m2);
}
```

error:
zig: <...>/zig/src/ir.cpp:10281: TypeTableEntry* ir_analyze_fn_call(IrAnalyze*, IrInstructionCall*, FnTableEntry*, TypeTableEntry*, IrInstruction*, IrInstruction*, bool, bool): Assertion `arg_var != nullptr' failed.
[3]    22448 abort (core dumped)  zig build_exe main.zig

I also tried:

```
pub fn main() -> %void {
    var x = &2;
    var y: u32 = *x;
}
```

error: 

<..>/ir.cpp:6980: bool ir_num_lit_fits_in_other_type(IrAnalyze*, IrInstruction*, TypeTableEntry*, bool): Assertion `const_val->special != ConstValSpecialRuntime' failed.
