[codeview] Revert inline line table change of r362264

Testing with debuggers shows that our previous behavior was correct.
The reason I thought MSVC did things differently is that MSVC prefers to
use the 0xB combined code offset and code length update opcode when
inline sites are discontiguous.

Keep the test changes, and update the llvm-pdbutil inline line table
dumper to account for this new interpretation of the opcodes.
