Clean up calls to prepare_one_comp_unit

Currently, prepare_one_comp_unit is called somewhat haphazardly: it is
mostly called when a CU is read, but some places manage to instantiate
a cutu_reader* without calling it, and some code (e.g.,
read_file_scope) calls it without really needing to.

Aside from contributing to the general confusion around CU reading,
this doesn't really cause problems in the current tree.  However, it
is possible for the DWARF reader to check the CU's producer before it
is ever set -- which is certainly unintended.
