We use both -long-option and --long-option in tests. Switch to --long-option for consistency.
In the "llvm-readelf" mode, -long-option is discouraged as it conflicts with grouped short options and it is not accepted by GNU readelf.
While updating the tests, change llvm-readobj -s to llvm-readobj -S to reduce confusion ("s" is --section-headers in llvm-readobj but --symbols in llvm-readelf).

Rather than creating a separate ".rdata" section distinct from the
customary ".rodata" in ELF, ".rdata" switches to the ".rodata" section.
This patch relands r305949 and r305950 with the correct commit message
and addresses nit raised during review.
