[MLIR] Any way to print debug for all patterns in a specific pass

[yuanfz98]

Hello Community,

I wonder if there is any way to print debug info for all patterns (/ ***IR Dump After Pattern Application *** ) in a specific pass.--debug is good but sometimes too verbose as it prints all.

Not from the command line, but in C++ you can enable/disable debug at will by changing the value of llvm::DebugFlag.
(can be set in a debugger as well)
