Currently all of LLDB is being compiled with -Wno-deprecated-declarations.
That's not desirable, especially as part of the LLVM monorepo, as we miss
deprecation warnings from LLVM and clang.
According to the git history, this was first introduced to suppress warnings
related to auto_ptr. Since then, other things have been deprecated and gone
unnoticed. This patch limits the flag to Host.mm which uses a handful of
LSApplication headers that have no replacement.

Subject: [PATCH] [lldb] Narrow scope of -Wno-deprecated-declarations (NFC)
Currently all of LLDB is being compiled with -Wno-deprecated-declarations.
That's not desirable, especially as part of the LLVM monorepo, as we
miss deprecation warnings from LLVM and clang.
According to the git history, this was first introduced to suppress
warnings related to auto_ptr. Since then, other things have been
deprecated and gone unnoticed. This patch limits the flag to Host.mm
which uses a handful of LSApplication headers that have no replacement.
