  -----------
  llvm-reduce: Fix invalid reductions for exceptions, tokens and swifterror

Copies the same special cases that bugpoint uses. Technically the
token condition is stricter than what the verifier enforces.

Part 1 of #58815

  Log Message:
  -----------
  llvm-reduce: Add reduction for invokes

Main thing I was unsure about was to whether try to delete the now
dead landing blocks, or leave that for the unreachable block reduction.

Personality function is not reduced, but that should be a separate
reduction on the function.

Fixes #58815
