Georgii Rymar 3d90a61cf2 [llvm-readobj] - Remove Error.cpp,.h and drop dependencies in the code.
We have Error.cpp/.h which contains some code for working with error codes.
In fact we use Error/Expected<> almost everywhere already and we can get rid
of these files.

Note: a few places in the code used readobj specific error codes,
e.g. `return readobj_error::unknown_symbol`. But these codes are never really used,
i.e. the code checks the fact of a success/error call only.
So I've changes them to `return inconvertibleErrorCode()` for now.
It seems that these places probably should be converted to use `Error`/`Expected<>`.

Georgii Rymar 506f89ce91 [llvm-readobj/elf] - Don't fail when dumping an archive with a member that can't be recognized.
Imagine we have an archive that has 3 objects in the following order:
<valid known object>,<unknown object> and <valid known object>.

Currently llvm-readelf/obj report an error and stops dumping in the middle.
This patch changes the error reported to warning.

Fangrui Song 536ba6373f [Object] Change ELFObjectFile<ELFT>::getFileFormatName() to use BFD names
Follow-up for D74433

What the function returns are almost standard BFD names, except that "ELF" is
in uppercase instead of lowercase.

This patch changes "ELF" to "elf" and changes ARM/AArch64 to use their BFD names.
MIPS and PPC64 have endianness differences as well, but this patch does not intend to address them.

Advantages:

* llvm-objdump: the "file format " line matches GNU objdump on ARM/AArch64 objects
* "file format " line can be extracted and fed into llvm-objcopy -O literally.
  (https://github.com/ClangBuiltLinux/linux/issues/779 has such a use case)

Affected tools: llvm-readobj, llvm-objdump, llvm-dwarfdump, MCJIT (internal implementation detail, not exposed)

Georgii Rymar fff9f049b2 [llvm-readobj][test] - Cleanup and split tests in tools/llvm-readobj folder.
tools/llvm-readobj currently contains tests that are either general for
all file types or that mix file types inside. This patch refactors
these test and leaves only general tests in that folder. All other
tests were moved to ELF/COFF/MachO and wasm accordingly.

I tried to minimize amount of changes, so most of the test parts
remained unchanged. Any further refactorings and improvements for
particular tests should be done independently from this patch.

Georgii Rymar dbf520f617 [llvm-readobj][test] - Move platform specific test cases and their inputs to separate folders.
This creates the next subfolders in the test directory:
"COFF", "ELF", "MachO", "wasm".

I've also removed platform specific prefixes, like "coff-*".
One unused binary was removed as well: `Inputs/relocs.obj.elf-mips`

James Henderson 5b27402bee [llvm-readobj]Fix error messages for bad archive members and add testing for archive handling
llvm-readobj's error messages were broken for bad archive members. This
patch fixes them, and also adds testing for archive and thin archive
handling within llvm-readobj.
