sparc64: fix crash in ABI code for { f64, f32 } struct
This would trigger a `Size::sub: 0 - 8 would result in negative size` abort,
if `data.last_offset > offset`.
This is almost hilariously easy to trigger (https://godbolt.org/z/8rbv57xET):
```rust
#[repr(C)]
pub struct DoubleFloat {
f: f64,
g: f32,
}
#[no_mangle]
pub extern "C" fn foo(x: DoubleFloat) {}
```
Tests for this will be covered by the cast-target-abi.rs test added in a later commit.
