URL: https://github.com/llvm/llvm-project/commit/1fd7dc40748b17d8fc47ef1ebede9df61e973056
DIFF: https://github.com/llvm/llvm-project/commit/1fd7dc40748b17d8fc47ef1ebede9df61e973056.diff

LOG: When dumping results of StackLifetime, it will print the following
log:

BB  [7, 8): begin {}, end {}, livein {}, liveout {}
BB  [1, 2): begin {}, end {}, livein {}, liveout {}
...

But it is not convenient to know what the basic block is.
So I add the basic block name to it.
