gdb/dwarf: move a bunch of DIE-reading functions to cutu_reader
With the hope of organizing things better and spotting patterns that
could lead to simplification, move all these functions to be methods of
cutu_reader. At least, this gives a good picture of what the entry
points for DIE and attribute reading are, by looking at what methods are
public.
Right now, my vague understanding of cutu_reader is that it does 3
things:
- it provides means to navigate and read the DIE tree, abstracting
things like whether the real content is in a DWO file or not
- it builds a dwarf2_cu object, for its own use but also for the use of
the caller
- it fills in missing details in the passed in dwarf2_per_cu
In the future, I'd like to separate those concerns. I think that
cutu_reader could retain the first one of those concerns, while the
other two could be done by other classes or functions, perhaps using
cutu_reader under the hood.
