Because we only ever call Pos_ReadDirect (and through that, DataRead<T>)

Browse Source 
from JIT generated code, the compiler may not get the heads-up to properly
prepare for run-time instantiation of those template functions.

Explicitly instantiating Pos_ReadDirect gets around that issue.

Also force DataRead* inline as gcc didn't always do that itself when the
DataRead functions in turn were called from (other) template functions.

I am far from a C++ language lawyer, so I cannot speak learnedly about the
correctness of this solution, but it works.

Dolphin.app built on OS X 10.6 now actually works on 10.5 as well.
