Wrappers for CTF/BTF to fetch information from GCC DWARF DIE.  Used in
ctfc.cc.

A CTF container does not store all debug information internally.  Some of
the info is fetched indirectly via the DIE reference available in each CTF
container entry.

These functions will be used by the CTF container to give access to its
consumers (CTF/BTF) to various debug information available in DWARF DIE.
Direct access to debug information in GCC dwarf structures by the consumers
of CTF/BTF information is not ideal.   
Source location information.   
CTF Types' and CTF Variables' Location Information.  CTF section does not
emit location information, this is provided for BTF CO-RE use-cases.  These
functions fetch information from DWARF Die directly, as such the location
information is not buffered in the CTF container.
