optReachable is used by the redundant branch optimizer to try and determine
if the successors of some dominating block can reach a target block.

In doing so, we can exclude paths from a successor that must pass
back through the dominating block to reach the target block.

This lets us remove some redundant branches in loops that we were missing
because we over-estimated reachability.

JIT: update optReachable with excluded block check

`optReachable` is used by the redundant branch optimizer to try and determine
if the successors of some dominating block can reach a target block.

In doing so, we can exclude paths from a successor that must pass
back through the dominating block to reach the target block.

This lets us remove some redundant branches in loops that we were missing
because we over-estimated reachability.

Simple example where this kicks in:

    public static int F(int x)
    {
        int r = 0;
        for (int i = 0; i < 50; i++)
        {
            if (x != 0) continue;
            r++;
            if (x != 0) continue;
            r++;
        }
        
        return r;
    }

Here the jit was unable to prove the second x != 0 was redundant. The flow in this case looks like

[edit: had the wrong graph here initially]

While trying to prove that the branch at D would make the branch at S1 redundant, the jit was considering the path S2 -> D -> S1, and so decided both S1 and S2 could reach S1, and hence the value of x != 0 at S1 was not known.

The fix is to designate D as an excluded block, so that the jit only considers paths that do not pass through D.

A moderate number of diffs, largely improvements. The largest improvements are cases where blocks with some substantial computation (newarr) are now unreachable.

The two largest regressions (see libraries pmi) are case where the RA creates large numbers of compensation blocks.
