  -----------
  [NFC][DebugInfo] Make MDNodeKeyImpl<DILocation>::Column 16 bits (#143399)

Column is limited to 16 bits in several places in the compiler:
DebugInfoMetadata.cpp#L87, LLParser.cpp#L4706, and more

Slight compile time improvement due to reducing `hash_combine` workload
in `MDNodeKeyImpl<DILocation>::getHashValue()`.

Positively affects compile time regardless of whether Key Instructions
is enabled. See PR for numbers.
