  Changed paths:
    M llvm/lib/Transforms/Scalar/DFAJumpThreading.cpp

  Log Message:
  -----------
  [DFAJumpThreading] Prevent pass from using too much memory. (#153193)

The limit 'dfa-max-num-paths' that is used to control number of
enumerated paths was not checked against inside getPathsFromStateDefMap.
It may lead to large memory consumption for complex enough switch
statements.
