For QtD, we need to get overloads of any function at compile time, not only
virtuals. Currently we are using a seemingly working dmd modified with the
patch attached. The patch also adds an 'identifier' trait, which allows to get
symbol identifiers without parsing the value of stringof.

Given the size and visibility of Qt, I think it's fair to leave this as
critical. I also voted for it :o).

Yeah, it actually is a blocker as you cannot use unpatched dmd for qtd. Thanks
for voting. In fact this functionality was requested in the bug report 2855.
The reason why we replace getVirtualFunctions with getOverloads rather than add
the new one is because the functionality that the former provides could easily
be achieved by filtering out the ouput of the latter with isVirtualFunction
trait. That way we don't bloat __traits.

The mentioned patch also provides isStaticFunction trait which we will
eventually need.

When implementing isStaticFunction, please make sure it returns true for any
function that doesn't require a context pointer (even if there is no explicit
STCstatic).

Thanks for applying the patch. Although there is a minor issue when building
dmd on linux with gcc:

traits.c:57: error: could not convert ‘f->FuncDeclaration::isVirtual’ to
‘bool’
traits.c:57: error: in argument to unary !

The fix is trivial, to add brackets to method call: f->isVirtual(). I didn't
know that dmc can compile function calls without brackets.
