It was reported (https://reviews.llvm.org/D65273#1612246)
that this test fails if the compilation directory contain
a "debug_" substring.
This should fix it.

When llvm-copy removes .dwo sections the index of symbol table,
the indices of the symbols and the indices of the sections which go
after the removed ones changes. That affects on SHT_GROUP sections,
which needs to be updated.
Initially this test used a precompiled object, I rewrote it to use YAML
and improved a bit.

Summary:
When llvm-objcopy sorts sections during finalization, it only sorts based on the offset, which can cause the group section to come after the sections it contains. This causes link failures when using gold to link objects created by llvm-objcopy.
Fix this for now by copying GNU objcopy's behavior of placing SHT_GROUP sections first. In the future, we may want to remove this sorting entirely to more closely preserve the input file layout.
This fixes https://bugs.llvm.org/show_bug.cgi?id=42052.

Summary:
As pointed out in D53667, our use of hyphens in flags can be inconsistent, mixing `-` with `--`. This change makes all long style flags use `--`.
Automatically changed via:
```
find test/tools/llvm-objcopy/ELF -type f | xargs sed -i 's/ -\([a-zA-Z]\{3\}\)/ --\1/g'
```
Two false positives were manually fixed/reverted.

In this diff the elf-specific tests are moved into the subfolder llvm-objcopy/ELF
(the change was discussed in the comments on https://reviews.llvm.org/D54674).
A separate code reivew wasn't sent for this change
since Phabricator is failing to create such a large diff.
Test plan:
make check-all
make check-llvm-tools
make check-llvm-tools-llvm-objcopy
