dwarf2read.c (dwarf2_find_base_address): Move definition.

Hi.

fyi, I've committed this.
It just moves the definition of one function to a different place.
Where it is now is right in the middle to two functions completely
unrelated to it, and I have further changes to make here.
So I'm moving it out of the way.
