Jozef Lawrynowicz 108ba4f4a4 [llvm-readobj] Refactor ELFDumper::printAttributes() 
The current implementation of printAttributes makes it fiddly to extend
attribute support for new targets.

By refactoring the code so all target specific variables are
initialized in a switch/case statement, it becomes simpler to extend
attribute support for new targets.

Georgii Rymar 137a25f04a [llvm-readobj, libSupport] - Refine the implementation of the code that dumps build attributes. 
This implementation of `ELFDumper<ELFT>::printAttributes()` in llvm-readobj has issues:
1) It crashes when the content of the attribute section is empty.
2) It uses `unwrapOrError` and `reportWarning` calls, though
   ideally we want to use `reportUniqueWarning`.
3) It contains a TODO about redundant format version check.

`lib/Support/ELFAttributeParser.cpp` uses a hardcoded constant instead of the named constant.

This patch fixes all these issues.

Georgii Rymar ade2fbbfb0 [llvm-readobj][test] - Merge 2 test cases together. 
This merges `invalid-attr-section-size.test` and `invalid-attr-version.test`
into `invalid-attributes-sec.test`.

This allows to have a single place where other related test cases can be added.
