Auto merge of #13148 - Manishearth:calc-null, r=emilio

Browse source 
Don't use mem::uninitialized() for making calc values

We had code relying on `nsStyleCoord::set()` being leaky (like it was
before we patched up the calc bindings). Added `nsStyleCoord::null()` for
this use case since it's not possible to construct directly anymore.
