[NFC][DebugInfo] Expand coverage of a RISCV test
This is a pre-commit for a patch (#134677) -- the test behaviour is not being changed, instead I've added "-v" to the llvm-dwarfdump commandline for --debug-line. This prints out how the linetable is encoded, not just what the linetable means, and it's important to illustrate that in the upcoming patch. I've separated out the llvm-dwarfdump line for .debug_info so that it's not affected by adding -v.
