  Log Message:
  -----------
  [Analysis] Add DebugInfoCache analysis

Summary:
The analysis simply primes and caches DebugInfoFinders for each DICompileUnit in a module. This
allows (future) callers like CoroSplitPass to compute global debug info metadata (required for
coroutine function cloning) much faster. Specifically, pay the price of DICompileUnit processing
only once per compile unit, rather than once per coroutine.

Test Plan:
Added a smoke test for the new analysis
ninja check-llvm-unit check-llvm
