Cranelift: Huge stack slot results in panic rather than an error returned from codegen

### `.clif` Test Case

```
test compile
target x86_64

function u0:12() system_v {
ss0 = explicit_slot 1073741824
ss1 = explicit_slot 16
ss2 = explicit_slot 1073741824
ss3 = explicit_slot 16
ss4 = explicit_slot 48

block0:
v21 = stack_load.i8 ss3
trap user0
}
```

### Steps to Reproduce

* Compile above test.

### Expected Results

Returns an error from `compile_function`.

### Actual Results

Panics with `Offset in NominalSPOffset is greater than 2GB; should hit impl limit first: TryFromIntError(())`

### Versions and Environment

Cranelift version or commit: 0.104

Operating system: N/A

Architecture: x86_64
