David Blaikie 725c4f71d1 dwarfdump: Correctly indentify the indicies for DWP records
The indicies are one-based, not zero-based, per the spec.

David Blaikie 20f52662d4 [llvm-dwp] Don't rely on implicit move assignment operator (MSVC won't synthesize one)

David Blaikie b073cb9be2 [llvm-dwp] Emit a rather fictional debug_cu_index
This is very rudimentary support for debug_cu_index, but it is enough to
allow llvm-dwarfdump to find the offsets for  contributions and
correctly dump debug_info.

It will need to actually find the real signature of the unit and build
the real hash table with the right number of buckets, as per the DWP
specification.

It will also need to be expanded to cover the tu_index as well.

David Blaikie 8e8dd57e0b dwarfdump: Add support for dumping the table contents of DWP indexes
This is a recommit of 252842 which was reverted in 252859. The issue was
using %s format specifier for a StringRef - used Format's
left_justify(StringRef, int) instead.

It'd be nice to have __attribute__((format(..))) on llvm::format, but
apparently it's only implemented for c-style variadics, not C++ variadic
templates. Perhaps we could fix that & conditionalize the attribute on
such...

David Blaikie 6400fc146e Mostly revert 252842 due to failures on some buildbots.
I imagine there's some UB in here somewhere, though Valgrind doesn't
seem to have picked it up (not sure if I have a working asan build right
now to test there).

GDB bot seems to be crashing:

Hexagon ELF bot is, presumably, just getting different output:

David Blaikie 65a8efe441 dwarfdump: First piece of support for DWP dumping
Just a tiny piece of index dumping - the header in this instance.
