[Lldb-commits] [lldb] add explicit default initialization to DemangledNameInfo to remove warning (PR #141790)

[Charles Zablit via lldb-commits]

https://github.com/charles-zablit created https://github.com/llvm/llvm-project/pull/141790

https://github.com/llvm/llvm-project/pull/140762 introduces some compilation warnings in `lldb/unittests/Core/MangledTest.cpp`. This patch adds explicit default initialization to `DemangledNameInfo` to suppress those warnings.

We only had the default initialization values to `PrefixRange` and `SuffixRange` because they are the only _optional_ fields of the structure.
