[mlir][liveness] fix bugs in liveness analysis (#133416)
This patch fixes the following bugs:
- In SparseBackwardAnalysis, the setToExitState function should
propagate changes if it modifies the lattice. Previously, this issue was
masked because multi-block scenarios were not tested, and the traversal
order of backward data flow analysis starts from the end of the program.
- The method in liveness analysis for determining whether the
non-forwarded operand in branch/region branch operations is live is
incorrect, which may cause originally live variables to be marked as not
live.
