[llvm-dwarfdump] - Dump the older versions of .eh_frame/.debug_frame correctly.
The issue is the following.
DWARF 2 used version 1 for .debug_frame.
(Appendix G, p. 416 http://dwarfstd.org/doc/DWARF5.pdf)
lib/MC now always sets version 1 for .eh_frame (and sets 1-4 versions for .debug_frame correctly):
https://github.com/llvm-mirror/llvm/blob/master/lib/MC/MCDwarf.cpp#L1530
https://github.com/llvm-mirror/llvm/blob/master/lib/MC/MCDwarf.cpp#L1562
https://github.com/llvm-mirror/llvm/blob/master/lib/MC/MCDwarf.cpp#L1602
In version 1, return_address_register was defined as ubyte, while other versions
switched to uleb128.
(p 62, http://www.dwarfstd.org/doc/dwarf-2.0.0.pdf)
Patch teaches llvm-dwarfdump about this difference.
