When bootstrapping the compiler with the `-Ysafe-init` flag, we would get the following error:
```
[error] -- Error: /*************/dotty/compiler/src/dotty/tools/dotc/core/tasty/TreePickler.scala:24:20
[error] 24 | pickler.newSection(ASTsSection, buf)
[error] | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
[error] |Call method TreePickler.this.pickler.newSection("ASTs",
[error] | dotty.tools.dotc.core.tasty.TreePickler.this.buf
[error] |) on a value with an unknown initialization. Calling trace:
[error] | -> val treePkl: TreePickler = new TreePickler(this) [ TastyPickler.scala:85 ]
[error] | -> class TreePickler(pickler: TastyPickler) { [ TreePickler.scala:22 ]
```
This supresses the warning for this case.
