This is a standalone repro case for golang/go#40879

• testdata contains logic to build an executable testdata/repro that:
  • has a .rela.debug_ranges section
  • has a DWARF DIE that uses DW_AT_ranges (to force this, I used a linker script to spread the code across 2 sections at different addresses)
• main.go contains logic that prints the PC ranges of testdata/repro
• test.sh will print the PC ranges using both the Go binary, and llvm-dwarfdump, to highlight the difference
• make will compile all binaries and run test.sh

Note: you need llvm installed (for llvm-dwarfdump). Alternatively you can change the test.sh script to use the regular dwarfdump.
