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.

Kai Wang 581ba35291 [RISCV] ELF attribute section for RISC-V. 
Leverage ARM ELF build attribute section to create ELF attribute section
for RISC-V. Extract the common part of parsing logic for this section
into ELFAttributeParser.[cpp|h] and ELFAttributes.[cpp|h].
