Igor Kudrin e94382ee37 [DebugInfo] Dump offsets in .debug_str_offsets according to the DWARF format (7/8).
The patch changes dumping of offsets in .debug_str_offsets sections so
that they are printed as 16-digit hex values if the contribution is in
the DWARF64 format.

Igor Kudrin f92a554516 [DebugInfo] Dump form values according to the DWARF format (2/8).
The patch changes dumping of DWARF form values which sizes depend on
the DWARF format so that they are printed as 16-digit hex values for
DWARF64.

Fangrui Song d840e54523 [DebugInfo][test] Fix section flags/type to avoid warning/error in the future
A future MC change may add a warning/error when a .section directive
specifies incorrect sh_flags/sh_type. Fix the tests to use correct
sh_flags/sh_type.

David Blaikie a17564c2f1 llvm-dwarfdump: Don't error on mixed units using/not using str_offsets
This lead to errors when dumping binaries with v4 and v5 units linked
together (but could've also errored on v5 units that did/didn't use
str_offsets).

Also improves error handling and messages around invalid str_offsets
contributions.

David Blaikie 79872a88a0 dwarfdump: Add a bit more DWARF64 support
This test case was incorrect because it mixed DWARF32 and DWARF64 for a
single unit (DWARF32 unit referencing a DWARF64 str_offsets section). So
fix enough of the unit parsing for DWARF64 and make the test valid.

(not sure if anyone needs DWARF64 support though - support in
libDebugInfoDWARF has been added piecemeal and LLVM doesn't produce it
at all)

Wolfgang Pieb f2b6915ed4 [DWARF] Fixing a bug in DWARF v5 string offsets tables where the length encoded the contribution
length excluding the table header. Instead it must encode the contribution length minus the length
field itself.

Wolfgang Pieb 6ecd6a8088 [DWARF v5] Rework of string offsets table reader
Reorganizes the DWARF consumer to derive the string offsets table 
contribution's format from the contribution header instead of 
(incorrectly) from the unit's format.

Wolfgang Pieb 8b1a175be6 [NFC] Change the string offsets table tests to generate the object on the fly
which enables us to remove the test scripts and object files from the repository.
