Georgii Rymar c3914bf28e [[lvm-readelf/obj] - Remove `tryGetSectionName` helper.
D91867 introduced the `tryGetSectionName` helper.
But we have `getPrintableSectionName` member with the similar
behavior which we can reuse. This patch does it.

Georgii Rymar 76a626b206 [llvm-readelf/obj] - Fix the possible crash when dumping group sections.
It is possible to trigger a crash/misbehavior when the st_name field of
the signature symbol goes past the end of the string table.

This patch fixes it.

Georgii Rymar 4dcdf0df31 [llvm-readobj] - Stop using `unwrapOrError` in `DumpStyle<ELFT>::getGroups()`
With this we are able to diagnose possible issues much better and
don't exit on an error.

Georgii Rymar 343dceb831 [llvm-readelf/obj] - Improve error reporting when dumping group sections.
Our code that dumps groups has 3 noticeable issues:
1) It uses `unwrapOrError` in many places.
2) It doesn't allow reporting unique warnings, because the `getGroups` helper is not
   a member of `DumpStyle<ELFT>`.
3) It might just crash. See the comment for `StrTableOrErr->data() + Sym.st_name` line.

In this patch I am starting addressing these points.
For start I've converted one of `unwrapOrError` calls to a unique warning.

Georgii Rymar a6436b0b3a [yaml2obj] - Make the 'Machine' key optional.
Currently we have to set 'Machine' to something in our
YAML descriptions. Usually we use 'EM_X86_64' for 64-bit targets
and 'EM_386' for 32-bit targets. At the same time, in fact, in most
cases our tests do not need a machine type and we can use
'EM_NONE'.

This is cleaner, because avoids the need of using a particular machine.

In this patch I've made the 'Machine' key optional (the default value,
when it is not specified is `EM_NONE`) and removed it (where possible)
from yaml2obj, obj2yaml and llvm-readobj tests.

There are few tests left where I decided not to remove it, because
I didn't want to touch CHECK lines or doing anything more complex
than a removing a "Machine: *" line and formatting lines around.

Georgii Rymar 066e209c9d [llvm-readelf/readobj] - Fix the behavior when a sections is included in two groups at the same time.
The current behavior was introduced by me in D37567 and it is a bit strange. It prints the
"Error: ...." message to the errs() manually and stops dumping the group section which has this error.
This behavior is consistent with GNU though, but it is very inconsistent with what the regular llvm-readelf
code usually does/prints, so I suggest to change the implementation:

1) Instead of printing "Error: ...." to errs() - just report a warning.
2) Try to continue dumping the section.
3) Merge broken-group.test to group.text.

This is what this patch does.

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`
