Feature Request: Support DWARF version 5

[nneonneo]

DWARF version 5 is out now, and is the default for newer GCCs. DWARF 5 should be upwards compatible, so the changes necessary to support it should be minimal.

Currently, loading a file with DWARF version 5 debugging data results in the following warning (and no debug information being loaded):

Error during DWARFAnalyzer import
Only DWARF version 2, 3, or 4 information is currently supported.
ghidra.app.util.bin.format.dwarf4.DWARFException: Only DWARF version 2, 3, or 4 information is currently supported.

@dev747368 Any progress to report on this? I may jump in and help depending on what the status is.

No progress to report on DWARF 5. There are some changes / improvements in the pipeline improving function parameter / local variable storage.

@dev747368 Has there been any progress on this issue? I'm encountering a lot of binaries with DWARF 5 debugging data, so it would be great if support for DWARF 5 was added to Ghidra.

Any progress on this issue? Support DWARF 5 please. >_<
