Faulty null check logic in haxe.Template

[Simn]

My null-checker complains about these:

https://github.com/HaxeFoundation/haxe/blob/development/std/haxe/Template.hx#L315
https://github.com/HaxeFoundation/haxe/blob/development/std/haxe/Template.hx#L321

if( p == null || p.s )
    throw p.p;

if( p2 == null || p2.p != ")" )
    throw p2.p;

If either p or p2 actually are null, the condition holds and the access on the p field is going to fail.
