<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">In cases like the following didn't return false, even though 'a' is not being used:
int f()
{
QByteArray a;
}
One would expect it to be a fast equivalent of !Declaration::uses().isEmpty(), but the result wasn't the same.
This change is also removing some calls in DUChain::uses()->hasUses (in case there's already a use in the local context) which I guess it's useful as well.
I'm putting this on review because I'm not sure the correct way to fix it is checking if it's <0.</pre>
