  -----------
  Implement a custom stream for LDBG macro to handle newlines (#150750)

This prints the prefix on every new line, allowing for an output that
looks like:
```
[dead-code-analysis] DeadCodeAnalysis.cpp:288 Visiting operation: func.func private @private_1() -> (i32, i32) {
[dead-code-analysis] DeadCodeAnalysis.cpp:288   %c0_i32 = arith.constant 0 : i32
[dead-code-analysis] DeadCodeAnalysis.cpp:288   %0 = arith.addi %c0_i32, %c0_i32 {tag = "one"} : i32
[dead-code-analysis] DeadCodeAnalysis.cpp:288   return %c0_i32, %0 : i32, i32
[dead-code-analysis] DeadCodeAnalysis.cpp:288 }
[dead-code-analysis] DeadCodeAnalysis.cpp:313 Visiting callable operation: func.func private @private_1() -> (i32, i32) {
[dead-code-analysis] DeadCodeAnalysis.cpp:313   %c0_i32 = arith.constant 0 : i32
[dead-code-analysis] DeadCodeAnalysis.cpp:313   %0 = arith.addi %c0_i32, %c0_i32 {tag = "one"} : i32
[dead-code-analysis] DeadCodeAnalysis.cpp:313   return %c0_i32, %0 : i32, i32
