Add code for processing version 5 DWP files (for use with DWARF v5).
The DWARF v5 Spec describes a (slightly) new format for V5 .dwp files.
This patch updates GDB to allow it to read/process .dwp files in the
new DWARF v5 format, while continuing to be able to read/process .dwp files
in the older V1 & V2 formats (older, pre-standard formats).
The two major differences between the V2 and the V5 format are:
- The inclusion of DWARF-v5-specific sections:
.debug_loclists.dwo
.debug_rnglists.dwo
- The .dwp section identifier encodings have changed. The table below
shows the old & new encodings. Notice the re-purposing of 5, 7 & 8
in particular.
