[llvm-readobj] - Remove deprecated unwrapOrError(Expected<T> EO).

[grimar]

Summary

This patch changes the code to use a modern unwrapOrError(StringRef Input, Expected<T> EO)
version that contains the input source name and removes the depricated version.

Aside: it's rather weird that invalid-e_shnum is being used to test an invalid e_phentsize...!

247

I think you can use -D here, right, like in %t10 case above and others?

test/tools/yaml2obj/elf-sht-symtab-shndx.yaml

6

Nit: use single-dash for -D.

Ditto

Why can't this check use [[FILE]]?

[MaskRay]

And a typo in the title: depricated -> deprecated

Initially this file was introduced to report "e_shnum should be zero if a file has no section header table" (D25090)
Then rL285738 changed it to "Invalid data was encountered while parsing the file." and
after that rL287081 changed it to "invalid e_phentsize".

This is a result of error catching code change multiplied by effect from having a black box precompiled binary committed.
(It was a binary produced using fuzzing as far I remember, so it could be broken in a many places)
We should just get rid of them all.

247

Yes, done.

429

It can. I did not like how -DFILE=%p/Inputs/corrupt-invalid-phentsize.elf.x86-64 looks like (too long),
but after another look, I am OK with it.

Same as @MaskRay's comment - can this use -DFILE here too?

237

Ditto.
