parse: allow switch/match/compound to start bin/cast expr

Minimal reproduction of bug:

$ cat > t.ha <<'EOF'
use os;

export fn main() void = {
	os::exit({
		yield 1;
	} - 0);
};
EOF
$ hare build t.ha
Syntax error: unexpected '-' at /tmp/t.ha:6:11, expected ',', ')'
Error: harec: exited with status 1
hare build: build failed
