Stack overflow compiling slice pattern for big array

The following fails with a stack overflow:
```rust
#![feature(slice_patterns)]

fn main() {
    match [0u8; 16*1024] {
        [..] => {}
    }
}
```
I see tests failing on miri's CI on Windows when the size is just `1024`, so my suspicion is that this code will fail to compile on Windows with a smaller slice -- but I do not have a Windows machine to test that.
