[Lldb-commits] [lldb] Convert ValueObject::Dump() to return llvm::Error() (NFCish) (PR #95857)

https://github.com/adrian-prantl created https://github.com/llvm/llvm-project/pull/95857
This change by itself has no measurable effect on the LLDB testsuite. I'm making it in preparation for threading through more errors in the Swift language plugin.

Subject: [PATCH] Convert ValueObject::Dump() to return llvm::Error() (NFCish)
This change by itself has no measurable effect on the LLDB
testsuite. I'm making it in preparation for threading through more
errors in the Swift language plugin.
