fixing another edge case related to comments + directives

[belav]

refactor docprinter a little
ignore some properties in syntaxNodeComparer so that it gives you a better indication of the code that is failing the validation

Okay, after seeing how this stack gets used, I retract my earlier comment that a List would be better.
In dotnet, a Stack implements IEnumerable, so we can do a read-only iteration through it to evaluate Fits().

Since Js doesn't have a native Stack structure, I can't speak for exactly what prettier used, but I'm guessing they couldn't iterate without mutating their stack, which is why they created a new one.

Nit: I wonder if this would look better as a:

case StringDoc { IsDirective: true }:
    ...

This is now a giant SwitchExpression which CSharpier doesn't do the greatest job formatting. #237

Why not just iterate over the input list with a foreach (and a .Reverse() if needed), since the only thing we care about is remainingWith?
I was hoping to do that, but when remainingCommands contains Group, Concat etc, then new commands get pushed onto commandToTests.

I'm thinking of doing the following. Fits will be a little more complex, but because of how often it can hit it is probably worth it.

1. Switching back to a stack in the Print method.
2. Treating the stack as read only in Fits, and iterating over it like you suggested.
3. Create another stack in Fits, which is used to push new commands when encountering Group, Concat etc.
4. Fits will iterate over remainingCommands, and inside of each iteration it will push/pop newCommands until newCommands is empty.

Although now that I type it out, I realize this approach will still be creating a new stack each time Fits gets hit... It could be modified to only create a stack if it needs to. I'll benchmark it and play around.

I did benchmark Stack vs List vs LinkList for this, and List/LinkList were quite a bit faster than Stack, but that was most likely because of the .Reverse used to create the Stack inside of Fits.
