657ee48bec Ignore instructions following a break from block in never_loop lint 
It is not sufficient to ignore break from a block inside the loop.
Instructions after the break must be ignored, as they are unreachable.
This is also true for all instructions in outer blocks and loops
until the right block is reached.

e9dffa3910 Fix a bug in never_loop when anonymous blocks are nested in named blocks 
The following code

```
loop {
    'a: {
        { }
        break 'a;
    }
}
```

was detected as a never-looping loop.

don't emit AlwaysBreaks if it targets a block 
Introduced an ignored_ids parameter.
Takes O(n^2) time in the worst case.

Can be changed to collect block ids in first phase,
and then filter with binary search in second.
