Short match

[Crell]

Adds support for short-circuiting a match() expression to match against boolean true. This is a convenience feature left out of the original match() RFC for simplicity but widely supported, so let's bring it back.

You'll need to handle the AST printer (look at test 009.phpt).

$a = 3;
assert(match {
    $a < 2 => 'small',
    $a == 3 => false,
    default => 'large',
});

What's the status here? This PR has an RFC label; if it needs an RFC, there should be one, but I'm not sure about that.

@cmb69 There's one in draft. I linked it above.

Nothing has happened here for a while so I'm closing this PR and the corresponding RFC. Feel free to reopen whenever you're ready to proceed.
